Stravomatic is an Android application designed to start and stop Strava rides and runs automatically when it detects that you are cycling or running. Developed by Colin Leroy, Stravomatic is a paid app that helps users avoid missing traces from their Strava activity feed. The app uses the accelerometer instead of GPS to save battery and distinguish between running and cycling.

The application may delay the activity start and shorten the activity time due to the detection parameters and the phone's various states of sleep, depending on the settings you choose. Several settings are necessary for Stravomatic to work correctly, such as exempting it and Strava from battery optimizations and allowing background GPS access to the Strava apps. On Android 10, the app requires the Screen Overlay permission to start activities in the background, and MIUI (Xiaomi) users must whitelist it in the MIUI Security application for automatic restart on boot.

Stravomatic is an excellent solution for those who forget to start their Strava rides and runs manually and don't want to miss any activity trace.
