What's the best continuous glucose monitor (CGM) service for a non-diabetic person interested in metabolic health?

If you’re non-diabetic and interested in metabolic health, I’d pick Nutrisense if you want the most hand-holding, but Dexcom Stelo by itself if you’re comfortable interpreting the data and want the best value.

One important caveat: CGMs are interesting for experimentation, but they’re not yet proven to improve health outcomes in otherwise healthy people. The ADA’s 2026 standards specifically say there isn’t sufficient evidence to use CGM to screen for or diagnose prediabetes/diabetes.

My ranking

Nutrisense stands out because it combines CGM data with access to a registered dietitian, rather than simply throwing glucose graphs at you. Current comparisons put its strength specifically in personalized nutrition guidance.

Levels is what I'd choose for someone who enjoys quantified-self data: its emphasis is more on analytics, meal responses and metabolic scoring than ongoing human coaching.

Stelo is probably the smartest way to start, though. You can get the sensor without committing to an expensive coaching subscription, which lets you answer questions such as “How does my glucose respond to oatmeal vs. eggs?” or “Does walking after dinner change my glucose?” Current comparisons identify Stelo and Lingo as the lower-cost, no-prescription options.

What I'd actually do

I'd buy a 14-day Stelo experiment first, rather than signing up for a $100–$300/month program.

Use it to investigate:

• How different breakfasts affect your glucose
• Whether a 10–20 minute walk after meals changes your response
• How late-night eating affects overnight glucose
• Your response to carbohydrates you eat regularly
• Whether sleep deprivation changes your glucose patterns

Then, if you find the data useful but don't know what to do with it, move to Nutrisense for the human coaching layer.

And don't obsess over individual spikes. Glucose naturally fluctuates, and there aren't well-established "optimal" CGM targets for healthy people comparable to the targets used in diabetes care. The recent evidence review also found no demonstrated health benefit from CGM use in people without diabetes, so I'd treat this as a short-term behavioral experiment rather than a medical necessity.

Bottom line: Best service: Nutrisense. Best value: Stelo. Best for quantified-self enthusiasts: Levels. Best if weight loss is your primary objective: Signos.

If you tell me your age, primary goal (longevity, weight loss, energy, fitness, preventing diabetes, etc.), and roughly what you're willing to spend per month, I can narrow it down to one and compare the current pricing/features.

What I'd actually do

I'd buy a 14-day Stelo experiment first, rather than signing up for a $100–$300/month program.

For a non-diabetic person focused on metabolic health, weight management, or fitness optimization, the CGM landscape has shifted dramatically. You no longer need to jump through hoops or get a workaround prescription.

The "best" service depends on whether you want standalone hardware (low cost, do-it-yourself) or a comprehensive coaching/software platform (expert analysis, deep lifestyle tracking).

1. Best Overall Standalone (No Prescription Needed)

• Dexcom Stelo: Best Overall Value & Simplicity
  • Cost: ~$99 per month (comes with two 15-day sensors).
  • The Vibe: Built specifically by Dexcom for non-insulin users and non-diabetics. It tracks glucose 24/7, updates every 15 minutes, and features a clean, straightforward app with AI photo food logging.
  • Pros: Excellent device reliability and accuracy, great integrations with Apple Health, Google Fit, and wearables like Oura, and no doctor’s visit required.

2. Best Budget Entry Point

• Abbott Lingo: Best for Low-Cost Experimentation
  • Cost: ~$89/month bundled, or as low as $49 for a single 15-day trial sensor.
  • The Vibe: Created by the makers of the FreeStyle Libre, Lingo is aimed at general wellness and behavioral habit-changing.
  • Pros: Sleek app interface, lowest price point if you just want to test the waters for two weeks.
  • Cons: The app uses a proprietary "Lingo Count" metric for meals that has mixed user reviews, and it doesn't support data sharing as easily as Stelo.

3. Best for Comprehensive Coaching & Dietitians

• Nutrisense: Best for 1:1 Expert Guidance
  • Cost: Premium subscription model (typically ranges from $225–$399/month depending on the plan length and coaching tier).
  • The Vibe: You get the CGM hardware bundled with a powerful app and, crucially, access to a dedicated registered dietitian who helps you interpret your glucose spikes, stress responses, and sleep patterns.
  • Pros: Ideal if you have the budget and want human accountability rather than just staring at raw data charts.

4. Best Dedicated Weight Loss & AI Engine

• Signos: Best for Fitness & Weight Management
  • Cost: Subscription-based pricing tiers similar to other coached platforms.
  • The Vibe: Signos pairs real-time CGM data with a heavy-duty predictive AI algorithm designed explicitly to optimize weight loss. It tells you precisely when to exercise or what foods to avoid based on your unique real-time metabolic curve.
  • Pros: Exceptional for active individuals or those trying to break through weight plateaus using dynamic, data-driven feedback.

Quick Comparison Summary

• Choose Dexcom Stelo if you want a reliable, hassle-free, lower-cost month-to-month tracker without extra fluff.
• Choose Abbott Lingo if you want the absolute cheapest single-sensor experiment.
• Choose Nutrisense if you want professional human guidance from a dietitian to make sense of the data.

To help narrow this down, let me know:

• Are you looking to spend under $100/month for a DIY tracker, or do you want human coaching/advanced software?
• Is your primary goal weight loss, athletic performance , or general longevity/anti-aging?

For a non-diabetic person focused on metabolic health, weight management, or fitness optimization, the CGM landscape has shifted dramatically. You no longer have to use expensive metabolic coaching subscriptions or jump through hoops to get a doctor's prescription.

The best choice depends on whether you want a direct, low-cost over-the-counter (OTC) biosensor or a high-touch program with professional guidance.

1. The Best Direct / Budget-Friendly OTC Options (Best Overall Value)

If you just want the data without paying a monthly markup for coaching you might not need, direct-to-consumer OTC biosensors are the clear winners. They require no prescription and link straight to an app on your phone.

• • Stelo Go to product viewer dialog for this item. (by Dexcom): Stelo by Dexcom Go to product viewer dialog for this item. is specifically designed for non-insulin users aged 18 and older. It is FDA-cleared for over-the-counter use, highly accurate, and costs around $84 to $99 a month. Each sensor lasts up to 15 days (a 2-pack covers a full month). Note: Because it's meant for non-diabetics, it intentionally does not blare urgent low-blood-sugar alarms, making it peaceful to wear day-to-day.
• • Lingo Go to product viewer dialog for this item. (by Abbott): Lingo by Abbott Go to product viewer dialog for this item. is Abbott’s direct competitor to Stelo . It translates minute-by-minute glucose data into a "glucose count" designed to help you curb sugar spikes, manage energy levels, and understand your body's specific metabolic responses. It operates on a similar 14-day wear cycle and competitive direct-to-consumer pricing.

2. The Best Guided Coaching Services (Best for Comprehensive Support)

If you want deep-dive analytics, educational modules, and—most importantly—access to a registered dietitian to help you interpret what your glucose curves mean relative to your sleep, stress, and workouts, a metabolic health platform is the way to go.

• • NutriSense: NutriSense is widely regarded as a top tier-service in this category. They handle the prescription coordination (using hardware like Dexcom or Libre sensors) and pair your data with a dedicated, credentialed dietitian who reviews your logs.
  • The Catch: It is significantly more expensive—typically ranging from $225 to $399 per month depending on the length of your commitment and coaching tier.

Quick Comparison to Help You Decide

To help narrow this down, are you looking for independent data tracking on a budget (OTC) or do you want 1-on-1 dietitian coaching to interpret your metabolic patterns?

If you're non-diabetic and interested in metabolic health, my top pick right now is Levels—but I’d choose the right tier rather than automatically signing up for the most expensive program.

My ranking

🥇 Best overall: Levels

Levels has evolved beyond simply putting a CGM on you: it combines glucose data with food logging, metabolic programs, bloodwork, AI analysis, and clinician review. That's a better fit if your goal is understanding and improving metabolic health rather than simply watching glucose graphs.

As of August 2026, its flexible plan is $15/month ($80/year) and lets you add CGM separately. Its current Stelo subscription is $89 per shipment for two sensors (~15 days each).

If you want the full program, Levels Core is $499/year and includes:

• 1 month of CGM
• Two essential lab panels covering 28+ markers
• Clinician review twice a year
• Food logging and AI insights
• Metabolic-health programs

That makes Core particularly interesting for someone who wants to use a CGM as part of a broader metabolic-health experiment rather than wearing one indefinitely.

🥈 Best value: Dexcom Stelo by itself

Dexcom's Stelo is probably what I'd choose if you're scientifically curious and don't need coaching.

It's an OTC CGM specifically cleared for people who don't use insulin, so you don't need to go through a traditional diabetes-management pathway. The FDA's current records continue to classify Stelo as an over-the-counter CGM for non-intensive glucose management.

The advantage is that you can spend much less and learn the basics yourself:

Eat something → observe glucose response → compare meals → look at exercise/sleep effects → change behavior → repeat. The disadvantage is that a CGM can generate a tremendous amount of data without necessarily telling you what matters.

🥉 Best if you want a nutrition coach: Nutrisense

Nutrisense is attractive if you want a person helping interpret your glucose patterns and translate them into dietary changes. Its program combines a CGM, app-based glucose insights and access to nutrition guidance.

I'd pick it over Levels if your main goal is nutrition coaching/accountability, rather than comprehensive metabolic-health tracking.

One important caveat

I'd be somewhat skeptical of anyone selling CGMs to healthy people as a proven longevity intervention. The technology is useful; the evidence that continuously monitoring glucose improves outcomes in otherwise healthy, non-diabetic people is still developing. Current comparisons of OTC CGMs likewise characterize the evidence for benefits in non-diabetics as emerging.

In other words, I'd use a CGM as a personal experiment, not as a device that tells you whether you're "healthy."

And don't obsess over individual glucose spikes. For metabolic health, I'd put considerably more weight on things such as A1C, fasting glucose, fasting triglycerides, HDL, blood pressure, waist circumference, fitness, sleep, and—depending on your situation—fasting insulin/ApoB than on whether one particular meal produced a 145 vs. 125 mg/dL peak.

What I'd do personally

Start with Levels + one month of CGM, rather than committing to a year of expensive sensors.

Use the month to answer specific questions:

1. Which breakfasts keep me stable?
2. How much does walking after meals change my response?
3. What happens when I eat carbs alone vs. with protein/fat/fiber?
4. Does late-night eating affect overnight glucose?
5. How do poor sleep and alcohol affect my response?
6. Are there foods I thought were healthy that produce surprisingly large excursions?

Then take the sensor off and see whether you've actually learned anything that changes your behavior.

If you tell me your approximate age, whether you're primarily interested in weight loss, longevity, athletic performance, or preventing diabetes, and how much you'd like to spend per month, I can narrow this down to the best specific CGM/service for you.

Eat something → observe glucose response → compare meals → look at exercise/sleep effects → change behavior → repeat. The disadvantage is that a CGM can generate a tremendous amount of data without necessarily telling you what matters.

🥉 Best if you want a nutrition coach: Nutrisense

Nutrisense is attractive if you want a person helping interpret your glucose patterns and translate them into dietary changes. Its program combines a CGM, app-based glucose insights and access to nutrition guidance.

I'd pick it over Levels if your main goal is nutrition coaching/accountability, rather than comprehensive metabolic-health tracking.

One important caveat

I'd be somewhat skeptical of anyone selling CGMs to healthy people as a proven longevity intervention. The technology is useful; the evidence that continuously monitoring glucose improves outcomes in otherwise healthy, non-diabetic people is still developing.

Start with Levels + one month of CGM, rather than committing to a year of expensive sensors.

Use the month to answer specific questions:

For a non-diabetic person focused on metabolic health, energy optimization, or weight management, the "best" service depends on whether you prefer pure data and tech integration or expert human coaching.

The market features dedicated over-the-counter (OTC) biosensors that do not require a prescription, alongside comprehensive third-party companion services.

1. Best for Nutrition-Focused Guidance & Dietitian Support: NutriSense

• How it works: Bundles CGM hardware (such as Dexcom /Abbott sensors) with a powerful proprietary app, AI tracking, and access to credentialed registered dietitians.
• Pros: Unmatched for personalized human insight; great if you want to understand why your glucose spiked after a specific meal or workout and how to fix it. It also syncs smoothly with fitness trackers like Oura and Apple Health.
• Cons: Significantly more expensive ($225–$399/month depending on the plan) because you are paying for the coaching and software ecosystem.

2. Best for Weight Loss & Activity Tracking:

• How it works: Utilizes Dexcom’s biosensor technology paired with an AI-heavy app designed specifically to forecast glucose spikes and drive weight management.
• Pros: Excellent app interface if your primary goal is shedding pounds or optimizing athletic/fasting windows. It turns raw data into proactive, real-time prompts around meals and movement.
• Cons: Premium pricing model (plans often start around $199/month), with less emphasis on deep 1-on-1 human nutritional counseling compared to NutriSense.

3. Best Standalone Over-the-Counter (OTC) Hardware: Dexcom Stelo

• How it works: FDA-cleared specifically for adults (18+) with type 2 diabetes or without diabetes who do not use insulin. No prescription needed; bought directly online or via subscription.
• Pros: 15-day sensor wear time (longer than standard 10-day prescription models), reliable hardware built on Dexcom's proven tech, and a lower price point (~$89–$99/month). It is also the most seamless OTC option if you want to pipe raw data into third-party apps.
• Cons: The basic Stelo app is relatively bare-bones compared to specialized metabolic coaching platforms, and it lacks high/low emergency alarms (which non-diabetics rarely need anyway).

4. Best Low-Cost Entry Point: Abbott Lingo

• How it works: An over-the-counter biosensor geared purely toward general wellness, habit-building, and understanding glucose "counts".
• Pros: Highly affordable—entry-level two-week options start around $49.
• Cons: The app ecosystem is designed strictly for self-guided beginners and is less friendly for exporting data or integrating with advanced health dashboards compared to Stelo.

To help narrow down which approach fits you best, tell me:

• Are you looking for hands-on coaching (dietitians) or just raw data tracking?
• What is your primary goal (weight loss, athletic performance, or general longevity)?

Yes. I’d separate “best CGM service” from “best CGM” because, for someone without diabetes, you’re mostly paying for the software/coaching layer rather than the sensor itself.

My pick: Nutrisense

For a non-diabetic person whose goal is metabolic health rather than primarily weight loss, I’d currently put Nutrisense first.

Its biggest advantage is that it combines the CGM with 1:1 dietitian/nutritionist support, rather than simply throwing glucose graphs and AI recommendations at you. Its current program includes two 15-day Dexcom Stelo sensors per month, an app with AI insights, and access to dietitian coaching. Current pricing starts around $149/month on a 6-month plan, versus about $215/month month-to-month.

How I'd rank the alternatives

Lingo is particularly interesting now. Abbott's OTC Lingo costs $54 for one 14-day sensor, $89 for two sensors/4 weeks, or $249 for six sensors/12 weeks. It includes the app, meal logging, recommendations and challenges, with no prescription required for adults not using insulin.

That changes the economics considerably: you can run a 2–4 week personal experiment for ~$54–89 instead of committing to a $150–200+/month coaching service.

What I'd actually do

If you're healthy and curious about metabolic health, I'd start with Lingo for 2–4 weeks rather than immediately signing up for an expensive annual CGM program.

Use it to run controlled experiments:

• identical breakfast with/without protein/fat
• high-carb vs. lower-carb meals
• 10–20 minute walk after eating vs. no walk
• early vs. late dinner
• different amounts of sleep
• strength training vs. rest days

Then look at patterns, rather than obsessing over individual glucose spikes.

If you find the data genuinely useful and want someone knowledgeable to interpret it, move up to Nutrisense. That's where the extra money becomes more defensible.

One important caveat

CGMs are excellent at showing your glucose response, but that doesn't mean every spike is unhealthy or that minimizing glucose variability automatically improves longevity. The evidence for using CGMs to optimize otherwise healthy, non-diabetic people is still developing.

And OTC devices are explicitly not intended to diagnose diabetes or for making medical decisions without professional guidance. Lingo, for example, says its data shouldn't be used to take medical action without consulting a healthcare professional. www.hellolingo.com The FDA has cleared Dexcom Stelo as an OTC CGM for adults 18+ who don't use insulin.

Bottom line:
Best service: Nutrisense
Best value / best first experiment: Lingo
Best for quantified-self analytics: Levels
Best if weight loss is the primary objective: Signos

If you tell me your country, approximate budget, and whether your priority is longevity, energy, body composition, athletic performance, or preventing diabetes, I can narrow this down to the best 2–3 options available to you.

For non-diabetics focused on metabolic health, energy optimization, or weight management, the CGM landscape falls into two categories: Direct-to-consumer over-the-counter (OTC) biosensors (which require no prescription) and software-plus-coach subscription programs (which package hardware with specialized apps and dietitian support).

The "best" option depends on whether you want raw, low-cost data or comprehensive human guidance to interpret it.

1. Best for Raw Data & Simplicity: Dexcom Stelo or Abbott Lingo

If you just want to put a sensor on your arm, track your glucose via an app, and pay standard consumer prices without a prescription or middleman, the FDA-cleared OTC options are the top picks.

• Dexcom Stelo
  • Best For: Tech integration and clean, straightforward tracking.
  • Pros: 15-day wear time per sensor, direct integration with apps like Apple Health, and built by Dexcom (industry-leading hardware accuracy). It is also unique among OTC options for making data-sharing with a healthcare provider straightforward.
  • Cons: It does not include high/low alerts (which you don’t need as a non-diabetic, but it's worth noting), and the native app is relatively bare-bones regarding deep lifestyle coaching.
• Abbott Lingo
  • Best For: Budget-conscious wellness seekers looking for behavioral habit changes.
  • Pros: Designed explicitly for general health and wellness, featuring a 14-to-15-day sensor life and an app geared toward building "glucose stability" habits and teaching you how your body responds to specific foods.
  • Cons: Exporting or sharing your data externally is more restricted than with Dexcom's ecosystem.

2. Best for Deep Insights & Software: Levels

If you want advanced analytics, educational content, and robust app features to make sense of your data, Levels is the premier choice.

• How it works: Levels pairs with top-tier hardware (like Abbott or Dexcom sensors) and provides a powerful, highly polished software platform. It grades your meals, tracks "metabolic flexibility," and aggregates your data into daily and weekly scores.
• Pros: Exceptional data visualization, deep educational library, logging features for meals/workouts/sleep, and smooth third-party wearable sync (e.g., Oura, Apple Health).
• Cons: More expensive than buying an OTC sensor outright, as you are paying a premium for the software ecosystem.

3. Best for Expert Guidance & Weight Management: NutriSense or Signos

If you are worried that looking at a squiggly glucose line will just confuse or stress you out, companion service programs provide the human element.

• NutriSense
  • Best For: One-on-one professional support.
  • Pros: Every subscription includes access to an assigned registered dietitian who reviews your data, answers questions, and helps you craft a personalized nutrition strategy based on your glucose trends.
  • Cons: It is the most costly route because you are paying for professional human labor alongside the hardware.
• Signos
  • Best For: Weight loss and exercise optimization.
  • Pros: Uses real-time glucose data combined with an AI-driven app to give you immediate prompts on when to eat or walk to optimize fat-burning and manage weight.
  • Cons: Subscription-heavy pricing model can scale up quickly if you want continuous, uninterrupted monitoring over many months.

Quick Comparison Summary

To help narrow down the best option for you, what is your primary goal (e.g., general longevity, athletic performance, weight management, or figuring out food sensitivities), and would you prefer just the raw data or guidance from a dietitian?

For a non-diabetic person interested in metabolic health, the “best” CGM service depends less on the sensor itself and more on how much interpretation and coaching you want. CGMs were originally developed for diabetes management, and their use for general wellness/metabolic optimization is growing, but the evidence for improving outcomes in otherwise healthy people is still developing.

Here are the strongest options:

My picks by type of user

Best overall for a beginner: Nutrisense
If you are new to CGMs and want to answer questions like:

• “Why do I crash after certain breakfasts?”
• “Does eating carbs at dinner affect my sleep?”
• “How does exercise timing affect glucose?”

…the value is having someone help interpret patterns rather than obsess over every spike. Nutrisense emphasizes CGM data plus registered dietitian guidance.

Best for a self-directed optimizer: Levels
Choose this if you enjoy tracking data and experimenting with:

• meal composition
• fasting windows
• exercise timing
• sleep/activity correlations

You’ll get more out of it if you like analyzing dashboards and changing one variable at a time.

Best value: buy a sensor without a premium coaching layer
If you mainly want a 2–4 week “learning experiment,” an OTC sensor like Stelo or Lingo may be enough. You can learn which foods produce unusually large responses without paying a recurring coaching subscription.

What I would avoid

• Using CGM data as a scorecard for every meal. Glucose varies naturally, even in healthy people.
• Chasing “perfect” glucose curves. A spike after exercise or a mixed meal is not automatically harmful.
• Assuming CGM data replaces standard metabolic markers. For a true metabolic health picture, things like fasting glucose, HbA1c, lipids, blood pressure, fitness, sleep, and body composition still matter.

A practical approach

For most healthy, curious people:

1. Wear a CGM for 4–8 weeks.
2. Keep notes on meals, sleep, stress, and workouts.
3. Look for repeated patterns, not single spikes.
4. Decide whether continued monitoring is actually changing your behavior.

If you tell me your main goal — fat loss, longevity, athletic performance, energy stability, reversing prediabetes risk, or just curiosity — I can narrow this to one or two choices.

For a non-diabetic person focused on metabolic health, the best approach depends on whether you prefer a direct-to-consumer over-the-counter (OTC) hardware option or a full-service coaching program with software insights . The top standalone OTC biosensors are Dexcom Stelo (costing roughly $99 per month for two 15-day sensors) and Abbott Lingo (around $49 per 14-day sensor ). If you want comprehensive software and human coaching interpretation, dedicated metabolic health services like Nutrisense or Levels integrate these sensors with advanced app platforms.

Over-the-Counter (OTC) Hardware Options

• Dexcom Stelo: The first FDA-cleared OTC CGM designed for adults not using insulin. It provides a 15-day wear time per sensor, tracks clear glucose patterns via your smartphone, and costs about $99/month. Note that it does not feature low-glucose alerts or alarms, as it is built for non-insulin users.
• Abbott Lingo: Specifically cleared as a general health and wellness tool for non-diabetics. It utilizes a 14-day wear cycle, focuses heavily on building metabolic flexibility through behavioral tracking, and represents a more budget-friendly hardware entry point at roughly $49 per sensor.

Full-Service Metabolic Platforms

• Nutrisense: Pairs top-tier CGM sensors with robust app analytics and—crucially—access to registered dietitians who help interpret your personal glucose data, spikes, and trends. Best for users who want personalized human feedback.
• Levels: Offers a software-first membership ecosystem that logs food, sleep, and exercise data against your real-time glucose responses to generate meal scores and deep metabolic fitness insights.

If you'd like to narrow this down, let me know:

• Are you looking for raw data tracking on a budget or expert coaching and diet advice?
• Do you have any specific metabolic goals (like weight management, athletic optimization, or longevity)?

If you’re not diabetic and your goal is metabolic health rather than glucose management, my pick in 2026 is Signos—with one important caveat: you probably don’t need a CGM continuously year-round.

My ranking

Why Signos: it combines the Dexcom Stelo sensor with an app that analyzes food, exercise, sleep and stress, gives personalized nudges, and provides access to dietitian support. Its current 6-month plan is $127/month with the site's August promotion, normally $169/month, and includes two sensors per month.

Signos uses Stelo, which is now an FDA-cleared OTC CGM for adults 18+ who aren't using insulin.

But there's a strong argument for Levels

If by "metabolic health" you mean more than glucose—lipids, inflammation, blood biomarkers, etc.—I'd actually choose Levels.

Its current Core plan is $499/year ($41/month) and includes essential lab testing, one month of CGM, clinician review twice a year, and its metabolic-health app. Complete is $1,999/year and adds comprehensive 100+ marker labs, two months of CGM, a nutritionist session and concierge support.

That makes Levels particularly interesting if you're trying to answer "Am I metabolically healthy?" rather than merely "Which foods spike my glucose?"

The sleeper choice: Lingo

If you're curious and want to run a 2–8 week experiment, I'd seriously consider Lingo by Abbott rather than paying $100–$200+ per month for coaching.

It's currently $54 for two weeks, $89 for four weeks, or $249 for 12 weeks (six sensors). It gives you minute-by-minute glucose data and an app with food/habit insights.

Similarly, Stelo by Dexcom is $99 for a one-month supply or $89/month on subscription, with up to 15-day sensors and an increasingly capable app.

One important reality check

For a genuinely healthy, non-diabetic person, the evidence that wearing a CGM continuously improves long-term health is still limited. CGMs can be fascinating for learning how your body responds to meals, sleep, exercise and stress, but normal glucose fluctuations aren't necessarily problems that need fixing.

I'd therefore use one as a short-term behavioral experiment, not as a permanent health scorecard.

If it were my money:

• Want coaching + easiest experience → Signos
• Want serious metabolic-health assessment → Levels
• Want to experiment cheaply → Lingo
• Want just the sensor/data → Stelo

If you tell me your age, whether your goal is weight loss vs. longevity vs. optimizing diet/exercise, and whether you already use an Apple Watch/Oura/Garmin, I can narrow this down to the best option for you.
