FitnessOverlays generates clean, customizable activity overlays from Strava data, designed for social sharing.
Strava’s built-in activity overlays are limited, mostly locked behind a premium paywall, and not optimized for export-quality sharing.
FitnessOverlays solves this by letting athletes create better overlays from their activity data without relying on Strava’s premium features.
- Secure OAuth connection to Strava

- Backend: Python (FastAPI)
