## Aperçu

FormCheck AI (formerly PureStrength) is an iOS app that analyses videos of your squat, bench press and deadlift and gives instant feedback on your lifting technique. It is built by Purestrength Limited and pairs on-device computer vision with a coaching-style feedback layer, so you get specific cues about depth, bar path, hip position and lockout instead of a raw number.

## Tarifs et offres

Free to download and use as of version 3.0 (January 2025), with optional in-app purchases. The app was previously subscription-based; verify the current pricing and any in-app offers on the App Store page for your region.

## Fonctionnalités clés et capacités

- **Deadlift form correction:** Track hip movement, shoulder position and lockout so you avoid a rounded back and get a clean pull.
- **Squat form analysis:** Depth monitoring plus alignment and balance alerts so you activate the right muscles on every rep.
- **Bench press guidance:** Feedback on bar path, control, grip and elbow position across the press.
- **On-device 3D analysis:** In-app 3D rendering and slow-motion playback let you replay each rep and see exactly where technique breaks down.
- **Form library and content:** Articles and videos on lifting technique, nutrition and recovery sit alongside a library of sample lifts.

## Cas d'usage principaux

- **Clean up the big three (Powerlifter):** Review every working set against the app's form checklist and catch hip shift, shallowness or a soft lockout before it becomes a habit.
- **Self-review between sessions (Strength coach):** Let lifters film their lifts and compare the app's cues against your own coaching notes between sessions.
- **Learn technique safely (Beginner lifter):** Use bar-path and depth feedback to learn a new movement pattern with objective reference points.
- **Return-to-lifting monitoring (Athlete returning from injury):** Track velocity-based programs and range of motion over time to monitor progress across a training block.

## Forces

- Detailed, lift-specific cues for squat, bench press and deadlift rather than generic rep counting.
- On-device processing keeps training videos private and works without a constant connection.
- 3D rendering and slow-motion replay make it easy to see exactly where form breaks down.
- Became free to use in 2025, removing the previous subscription barrier.
- Runs on iPhone, iPad, Mac (Apple silicon) and Apple Vision.
- Regular updates from an active developer.

## Limites

- Focused on only three lifts (squat, bench press, deadlift), so it is not a general-purpose workout tracker.
- Analysis quality depends on how well you frame and film your set; poor angles produce weaker feedback.
- Larger download (~495 MB) because the computer-vision models run on the device.
- iOS/visionOS only — no Android or web version.
- Text feedback style may feel terse compared with a human coach.
