FormLens: AI Form Check Coach
Workout Tracker & Gym Log
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: train in kg or lbs — your pick, everywhere. Plus in-app subscription management, honest running metrics and rotated-video uploads.
Film a lift, get an AI form score, and fix your weak points with a plan built for you. FormLens Pro comes with a 7-day free trial.
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.

This update makes FormLens faster to start and better in the gym:

1.2.18 Jul 6
New programs, smarter plans, and a lighter app.
• 4 new training programs — 5/3/1, nSuns, GZCLP, and the Arnold Split, built around the lifts FormLens scores.
• Corrective plans, upgraded — swipe through the full program before you commit, and land right on your plan when you start it. Now reachable straight from your results and the Workouts tab.
• You're in control of your AI plans — pick exactly which form analyses shape your generated and corrective plans.
• Smaller download — we trimmed about 25 MB, so FormLens installs faster and takes up less space.
• Polish & fixes — cleaner exercise names, and canceling a recording mid-set no longer kicks off an analysis.
Keep filming, keep improving. As always, thanks for the feedback.
1.2.17 Jun 27
This update makes FormLens smarter about your reps and your progress:
• Manual rep marking — if the AI can't auto-count a rep (tricky angle, odd
lighting), just scrub the video and tap to mark each one. No more 0-scores.
• All-new Stats: track your Form Score over time, see sets & volume per muscle
group, and tap any chart to read exact numbers.
• Training Activity & streaks — see your weekly consistency at a glance.
• Celebrate the wins — personal-record confetti, streak milestones, and a
"this vs. last time" comparison after every analysis.
• Plus polish and stability fixes throughout.
Keep filming, keep improving. Questions or ideas? We'd love to hear them.
1.2.16 Jun 16
A big update focused on getting you to better form, faster.
• Redesigned onboarding that builds a plan around your goal and the weak points our AI finds in your form
• New progress tracking front and center — streaks, PRs, and monthly reports
• Smarter workout reminders so you never miss a session
• A more polished, premium experience throughout
Film a lift, get your form score, and let's fix it together.
