## Forma

Forma is a lightweight web tool for runners who want a second opinion on their mechanics without booking a gait lab or a physio session. You upload a video of yourself running, and the service runs an AI-powered analysis that frames the results in the language of running efficiency and injury prevention. The site describes the analysis as expert-level and notes that it was designed by sports medicine professionals, which sets expectations that the feedback is coaching-oriented rather than a bare measurement readout.

The appeal is accessibility. Traditional running gait analysis often requires finding a specialist, booking time, and paying a consultation fee. Forma collapses that into an upload, which makes it realistic to check your form after a training block change, after an injury layoff, or when a new shoe or surface alters how you move.

Because the product is free and the interface is deliberately minimal, Forma fits best as a recurring self-check rather than a one-off appointment. It does not replace a clinician when you have genuine pain, but it can help you notice patterns, compare how you look over time, and prepare better questions for a coach or medical professional.

**Pricing & Plans:** Free. The site presents the running analysis at no cost, with no published subscription or per-analysis pricing visible.

- **AI running form review:** Submit a video of your running gait and receive an automated analysis of your technique rather than a raw recording with no interpretation.
- **Sports-medicine framing:** Analysis is presented through a sports medicine lens, focusing on efficiency and injury-prevention cues rather than generic fitness scoring.
- **Simple video upload:** A dedicated upload flow keeps the process to a single step: capture your run, upload the clip, and get feedback.
- **Free to use:** The tool is offered at no cost, making it practical to re-analyze your form repeatedly as your training evolves.

**Strengths:** Free access removes the cost barrier that usually accompanies gait analysis; Designed with input from sports medicine professionals rather than built as a generic pose estimator; Feedback is framed around practical running efficiency and injury prevention; Very low friction: just record and upload a video

**Limitations:** As a browser app it depends on JavaScript, so it will not work with scripts disabled; The site offers limited written detail about the underlying model and its accuracy; It is guidance for self-directed training, not a clinical assessment

## PureStrength (FormCheck AI)

PureStrength, now listed on the App Store as FormCheck AI, is a video-based AI personal trainer for the big three powerlifting movements. You record a working set on your iPhone, the app tracks the barbell and key joint positions frame by frame, and it returns plain-language coaching cues on what went right and what needs fixing. Because the models run on the device, your clips are processed locally rather than uploaded to a server.

The strongest part of the app is the depth of its per-lift feedback. For the deadlift it watches shoulder positioning, hip drive and lockout; for the squat it monitors depth, alignment and left/right balance; for the bench press it looks at bar path, control, grip and elbow position. Later releases extended this to bent-over rows and bicep curls, and added on-device 3D rendering so you can rotate a lift and inspect the trajectory of the bar.

The app comes from Purestrength Limited, a small studio that also publishes Larry AI, Deepbarbell and Qutie. It sits firmly in the strength-training niche rather than general fitness: if you compete in powerlifting or take your squat, bench and deadlift seriously, the specific cues are genuinely useful, while anyone looking for a full workout log or calorie tracker will want something broader.

**Pricing & Plans:** 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.

- **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.

**Strengths:** 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.

**Limitations:** 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.
