FormLens: AI Form Check Coach
Squat, Bench, Deadlift & Run
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Film a set to get a Form Score and the one thing to work on next. Film that lift again and coaching can compare it with last time. Your videos never leave your phone.
FormLens is an AI form check app for lifting and running. Film your squat, bench press, deadlift, overhead press or run and get a 0–100 form score with the fix.
Your workout videos never leave your phone. FormLens reads joint positions from the video on your device and sends the measurements taken from them for coaching — never the video, never a photo.
Why just log your numbers when you can log your quality? Most workout trackers only tell you how much you lifted. FormLens tells you how well you lifted.

group, and tap any chart to read exact numbers.
• Training Activity & streaks — see your weekly consistency at a glance.

"this vs. last time" comparison after every analysis.
