## What is MotionLens?

MotionLens turns your phone into a personal AI fitness coach — no wearables, no sensors, just your camera.

Point your camera at yourself, start a workout, and MotionLens uses real-time pose detection to track your body movement and automatically count your reps. A live skeleton overlay shows exactly what the AI sees, so you always know you're being tracked accurately.

WHY MOTIONLENS

• Automatic rep counting — no more losing count mid-set
• Real-time skeleton tracking overlaid on your camera feed
• Works with front or back camera
• Audio and haptic feedback on every rep, and a special cue when you hit your target
• On-screen guidance if you step out of frame or aren't fully visible

SUPPORTED EXERCISES

• Push-ups — tracked via elbow angle
• Squats — tracked via knee angle
• Bicep curls — tracked via elbow angle

More exercises are on the way.

TRACK YOUR PROGRESS

• Daily dashboard with today's reps, workout streak, and quick-start shortcuts
• Weekly and lifetime stats: total workouts, total reps, active days
• Full workout history with duration and reps per session
• Set a daily reps goal and watch your progress bar fill up

BUILT FOR FOCUS

MotionLens uses a clean, distraction-free dark interface with a signature neon-green accent, so you can stay focused on your form and your reps — not on fumbling with the app.

PRIVACY FIRST

All pose detection runs directly on your device using on-device machine learning. Your camera feed is never uploaded or stored — MotionLens only saves your workout stats (reps, duration, exercise type) locally so you can track your progress over time.

Whether you're warming up, grinding through a home workout, or just trying to stay consistent, MotionLens keeps count so you can focus on the movement.

Download MotionLens and let your camera be your spotter.
