How does the analysis work?

SkiCoach AI uses on-device CoreML pose detection to analyze your skiing technique from video. The entire analysis pipeline runs locally on your iPhone -- no data is sent to any server. The app detects 14 body joints and evaluates your form across 8 biomechanical metrics using over 50 scoring factors.

Is my data sent anywhere?

No. All video processing, pose detection, and analysis happen entirely on your device. Your videos, session data, and training progress never leave your iPhone. The only external connections are Apple Health (workout export, with your permission), Apple WeatherKit (weather conditions), and Apple StoreKit (purchase verification).

What devices are supported?

SkiCoach AI requires an iPhone running iOS 17.0 or later. For the best experience, we recommend iPhone 15 Pro or newer, which offer faster on-device ML processing.

How do I restore purchases?

Open the app, go to Settings, and tap Restore Purchases. Your previous purchases will be restored using your Apple ID. Make sure you are signed in with the same Apple ID you used for the original purchase.
