Which fitness apps use AI to count reps and correct form via camera?

Yes. There are now several apps that use your phone camera + computer vision/AI to count reps and give form feedback in real time.

Best options right now

Tempo is one of the more established options. Its system uses movement tracking and AI to provide real-time form feedback, although form feedback isn't available for every exercise.

For a phone-only experience, newer apps are particularly interesting:

• Form Coach automatically counts reps and gives a 0–100 form score plus live cues such as correcting knee or hip position. It currently lists 38 exercises and performs the processing on-device.
• FORMFIT claims 200+ exercises, real-time pose analysis, automatic reps, form scores, and voice coaching.
• Formright tracks movements through the camera, counts only valid reps, and provides exercise-specific coaching. It says camera processing stays on the device.
• Hoppa is aimed specifically at real-time correction: you put your phone down, and it watches your body and gives cues while you're performing the rep.
• Repmirror is another cross-platform option that explicitly combines rep counting, form scoring, and spoken corrections.
• FormLab is particularly interesting if squat form is your priority. It uses the iPhone camera to detect issues including knee valgus, insufficient depth, forward lean, heel rise, asymmetry, and butt wink.

One important caveat

“AI form correction” varies considerably between apps. A system may reliably detect squat depth or knee position but be much less reliable at judging something like back position during a heavy deadlift. Current consumer camera systems are best viewed as an additional feedback mechanism rather than a replacement for a qualified trainer, especially with heavy compound lifts.

If you tell me iPhone or Android, and whether you care most about weightlifting, bodyweight exercises, running, or general workouts, I can narrow this down to the 3 best apps and compare their prices/features.

Several mobile and hardware-integrated fitness applications use artificial intelligence and your device's camera to automatically count reps and analyze posture or form in real time.

Popular AI Camera Fitness Apps

• Firefly Fitness: Uses your phone's front or rear camera to track rep-based movements (like push-ups and squats) as well as static yoga poses, giving live audio and visual form corrections.
• GymCam: Focuses on precise, automated camera-based rep counting and tracking for various gym exercises, overlaying data directly onto recorded sets without manual tapping.
• Body Park Atom: Pairs an AI-powered wide-angle smart camera setup with software to track your entire body via computer vision, providing both live rep tracking and vocal form correction.
• Custom/Indie MediaPipe Apps: Many developers build lightweight computer-vision trackers using frameworks like Google's MediaPipe to handle rep tracking and form validation locally on mobile devices.

Comparison of Features

Are you looking for an app that runs strictly on your mobile phone or one that connects to smart home gym hardware/mirrors?

Several mobile and hardware-software fitness applications use artificial intelligence and computer vision through a device camera to count reps and evaluate or correct exercise form in real time.

Would you like to know more about how computer vision tracking works on mobile devices , or are you looking for apps specialized in a specific workout style (like yoga, weightlifting, or bodyweight training)?

Yes. A number of apps now use computer vision/AI through your phone’s camera to count reps and give form feedback. The best options differ quite a bit in how sophisticated the form analysis is.

My picks

🥇 Best overall phone-only: Tooki It uses the phone camera to track your movement, count reps, assess depth and tempo, and provide real-time form cues. Processing is performed on-device.

🥈 Best if you're primarily lifting: FormLab Particularly interesting for squats: it analyzes things such as knee valgus, insufficient depth, forward lean, heel rise, asymmetry and butt wink. It also automatically counts reps and provides per-rep feedback. It's currently iPhone-only.

🥉 Best Android option: Form Coach It uses the phone camera to automatically count reps and gives a 0–100 form score plus spoken corrections such as correcting hip position or squat depth. It currently lists 38 exercises.

Best free/simple option: Cadence It runs pose detection on-device and currently handles push-ups, planks, squats, crunches and glute bridges, with live form correction for push-ups and alignment feedback for planks.

Best hardware-assisted option: Tempo Tempo's 3D Vision system maps joints and movement and provides real-time form feedback and rep counting. It's more of a complete home-gym ecosystem rather than simply downloading an app and pointing your existing phone at yourself.

One important caveat: "AI form correction" isn't equivalent to having a human trainer watch you. These systems are generally good at measurable things like squat depth, joint angles, tempo, alignment and range of motion, but can miss subtler issues—especially with complex barbell movements or when your body is partially occluded.

If you tell me iPhone or Android + what exercises you care about (e.g. squats, bench, deadlift, push-ups, dumbbells), I can narrow this down to the 2–3 best apps for you.

Several fitness apps now use AI/computer vision through your phone camera to track body movement, automatically count reps, and give form feedback. The best options depend on whether you want bodyweight training, gym lifting, or a full AI coach.

A few other notable ones:

• CoachAI — camera-based rep counting and real-time form feedback.
• doReps — focuses on counting only “clean” reps and analyzing technique after workouts.
• Push-up Track — specialized for push-ups with depth, lockout, and stability scoring.

A few things to watch for:

• “AI form correction” varies a lot. Some apps only detect joint angles (e.g., squat depth), while others provide actual coaching cues.
• Camera angle matters. Most require your full body to be visible, good lighting, and a stable phone position.
• Heavy barbell lifts are harder. Squats, push-ups, lunges, and curls are much easier for AI to evaluate than deadlifts, cleans, or complex movements.

If you want the closest thing to a virtual personal trainer, I’d look first at Tooki, Hoppa, Strive AI, or Repmirror. If you mainly want accurate rep counting for gym exercises, Formright is more focused on that.

Several fitness apps use computer vision and AI pose-estimation models via your smartphone or tablet camera to track joint angles, count reps, and critique your posture in real time.

Prominent Camera-Based AI Fitness Apps

• Ray — Features real-time conversational voice coaching paired with computer-vision rep counting and instant form feedback. You prop your phone up, and the AI actively talks to you, tracks your reps, and flags technique issues.
• Zing Coach — Uses an AI-powered feature called Zing Vision , which turns your device camera into a motion tracker to evaluate your form, deliver postural feedback, and score your performance.
• Strive (AI Home Workout) — Combines bodyweight home-workout programming with live camera-based form correction and automatic repetition counting.
• Fitnit — Focuses heavily on minimalist and home setups, utilizing real-time AI pose detection via your phone camera to count reps (for push-ups, squats, pull-ups, and curls) while screening for proper form.
• Gymaholic (AI Form Checker) — Allows you to record or upload exercise videos from a side angle; the AI then analyzes your range of motion, tempo, alignment, and stability, giving you a detailed performance score.
• PUSHapp — A lightweight, camera-based push-up counter that validates rep depth so that incomplete or half-reps are ignored by the tracker.
• GymCam — A dedicated camera rep-counting app for Android that tracks full-body movements in real time and lets you remotely start/stop sets without touching your screen.

If you're looking for a specific type of workout, tell me:

• Are you training at home with bodyweight or at a gym with weights?
• Do you prefer live, real-time audio feedback while you move or video review after your set?

I can help you pick the best app for your setup.

Several fitness apps now use AI computer vision (your phone camera) to track body movement, count reps, and give form feedback. The quality varies a lot: some are excellent for basic bodyweight movements, while others aim for more complete “AI personal trainer” experiences.

A few notes before choosing:

• For lifting weights (bench, deadlift, barbell squat): camera AI is improving, but many apps are still much better at bodyweight exercises because the phone can more easily see joint angles and range of motion.
• For push-ups, squats, lunges, planks, burpees: these apps tend to work best.
• Look for:
  • real-time voice cues (not just an after-workout score)
  • exercise coverage that matches your routine
  • on-device processing if privacy matters
  • ability to place the phone far enough away for full-body visibility

If you want the closest thing to a free AI personal trainer, I’d compare Tooki, Repmirror, OptiRep, and Neon Pose first. If you mainly want strength training with weights, the shortlist changes.

Several fitness apps use on-device computer vision and AI pose detection (such as MediaPipe or QuickPose frameworks) via your smartphone or tablet camera to automatically count reps and analyze your form in real time.

• Kemtai — Widely considered one of the most advanced software-only options for home workouts, it tracks body points via a device camera to offer deep postural error callouts (such as tracking knee valgus or hip drops) alongside accurate rep counting.
• REP AI — Available on the Google Play Store, this on-device AI app tracks your body posture to automatically count repetitions, measure movement speed, and actively flag bad form or posture mistakes in real time.
• GymCam — Available on iOS and Android, this app uses computer vision to track and count reps for general bodyweight movements, jumping rope, and overlays the live rep count onto automatically recorded workout videos.
• Elxis — An AI-driven app that watches and counts exercises like pull-ups, push-ups, and squats from your device's camera, automatically baking a repetition watermark directly into video recordings of your sets.
• Fitnit — A mobile app featuring real-time AI pose detection that counts proper-form reps for movements like push-ups, squats, and bicep curls while offering corrective feedback.
• Onyx — Uses your phone's front camera to track body mechanics, count your repetitions, and deliver live form correction adjustments during home fitness sessions.

Would you like to narrow these down by operating system (iOS vs. Android) , or are you looking for apps specialized in a specific workout type like bodyweight/calisthenics vs. heavy lifting?

Several mobile and smart-device fitness applications leverage on-device AI and computer vision (using your phone, tablet, or smart-display camera) to track skeletal keypoints, count reps hands-free, and analyze or correct form in real time.

The notable apps and platforms utilizing this technology include:

• Strive (AI Home Workout) — Combines camera-based pose estimation for live form correction and automatic repetition counting with structured, adaptive home and bodyweight training programs.
• REP AI: Workout Rep Counter — Uses local AI pose detection via your smartphone camera to track movement speed, count sets and reps automatically, and flag common posture or form mistakes.
• Fitnit — An AI-powered pose-detection app focused on bodyweight movements (like push-ups, squats, and crunches) that counts only reps performed with proper form and offers real-time adjustments.
• Firefly Fitness — An AI personal trainer app providing real-time form feedback via the phone's camera for both dynamic rep-based exercises (squats, push-ups) and static holds (planks, yoga poses).
• GymCam / Elxis / RepVision — A group of utility-focused camera apps (available across iOS and Android) designed to track specific movements—ranging from general calisthenics and pull-ups to jump rope—by overlaying real-time AI counting and analyzing performance metrics directly on video feeds.
• Tempo — A prominent hybrid hardware/software platform that uses a specialized 3D depth-sensing camera paired with AI to evaluate lifting form and count reps (though it relies on dedicated home-gym equipment rather than just a standard mobile phone).

Are you looking for an app for bodyweight/home workouts or heavy barbell/gym lifting , and do you prefer an option that uses just your phone's camera vs. a wearable/smart TV setup?

Yes. There are several now that use your phone camera/computer vision to count reps and give real-time form feedback.

The ones I'd look at first

1. Ray — best overall AI trainer
Ray uses the iPhone camera to watch your movement, count reps and provide form guidance, while also adapting your workout based on fatigue, available time, and performance. A recent hands-on review found its camera rep counting surprisingly accurate.

2. Kemtai — best for serious form feedback
Kemtai uses computer vision to analyze movement and provide real-time corrective guidance. Its platform claims 2,000+ exercises and variations and works with ordinary camera-equipped devices rather than requiring special hardware.

3. Tooki — interesting cross-platform option
Tooki specifically advertises live rep counting, depth/tempo analysis and real-time form cues, with processing done on the device. It supports both iOS and Android.

4. OptiRep — best if you want a numerical form score
It analyzes 33 body landmarks, automatically rejects bad reps, scores technique from 0–100, and gives spoken corrections such as going deeper or keeping your back straight.

5. doReps — simplest "camera as rep counter" approach
It focuses on automatically counting clean reps and giving live form cues for exercises such as squats, push-ups, lunges, burpees and pull-ups.

One important caveat: "AI form correction" varies considerably between apps. Some are primarily detecting whether you've reached the required range of motion, while others attempt to identify specific issues such as back position, knee alignment, tempo, or symmetry. Camera angle, lighting and whether your whole body is visible can also substantially affect accuracy.

If you tell me iPhone or Android + the exercises you care about (e.g. squats, bench press, deadlifts, curls), I can narrow this down to the 3 best apps for your use case, including price and privacy.
