SkiCoach.app

Introduction to SkiCoach.app

SkiCoach.app is a mobile application for iOS and Android that provides on-device, real-time ski technique analysis using the sensors already in a smartphone. It delivers a 0–100 technique score, voice coaching, and progress tracking without requiring additional hardware or a network connection.

Designed for recreational and advanced skiers who want objective feedback, the app operates fully offline, performs all AI processing locally, and does not upload personal data. It is built with privacy in mind and supports audio coaching in English, German, French, and Italian.

Key Takeaways

• 100% on-device processing with no data uploaded; works without cellular coverage
• Real-time technique scoring (0–100) analyzing turn quality, edge control, and movement patterns
• Audio coaching with adjustable intensity in four languages (EN, DE, FR, IT)
• Auto-start detection based on speed and altitude; works from a pocket
• Rhythm Coach for turn cadence estimation (BPM) and music tempo alignment
• Battery optimization modes with stated operation estimates of approximately 4/6/8+ hours
• Fall detection with prompts and emergency contacts available in the free tier
• Data export to CSV, GPX, and JSON; GPX files can be uploaded to Strava

How SkiCoach.app Works

After the phone is placed in a pocket, SkiCoach.app detects when skiing begins using speed (e.g., above 10 km/h) and altitude changes. It uses the device’s motion and location sensors to record runs while managing power consumption through configurable battery modes.

During skiing, on-device models analyze movement patterns turn by turn to compute a 0–100 technique score and identify areas for improvement such as edge control and turn consistency. Optional audio coaching provides feedback at different intensities, and Rhythm Coach estimates turn cadence in BPM to help maintain a steady rhythm or align with music tempo.

Post-run, the app presents results, history, and statistics to monitor progress over time. Users can export data in CSV for analysis, GPX for mapping and services such as Strava, and JSON for development or integration needs. All processing and storage remain on the device.

Core Benefits and Applications

• Technique improvement: Objective scoring and targeted tips for refining turns and edge control.
• Training anywhere: Fully offline operation is suitable for areas with weak or no reception.
• Privacy-first workflows: No cloud connectivity or tracking, with GDPR-friendly design.
• Hands-free operation: Auto-start detection and pocket use reduce friction during sessions.
• Structured progression: History, results, and charts help track long-term improvement.
• Flexible data use: Export options support personal analysis, sharing, and third-party platforms via GPX.
