BaseMile

BaseMile is a free heart rate running coach for building your aerobic base. It runs entirely on your phone. Pick a Long, Medium or Brief run and BaseMile tells you the heart rate band to hold. Pair a Bluetooth chest strap and a spoken coach keeps you in that zone, so you can run by feel without staring at your wrist. ON THE RUN - Live heart rate, zone, pace, distance, cadence and elevation - A spoken coach that warns you before you drift over your ceiling - Voice Mode: a strict heart rate band with simple KEEP, LIFT and EASE cues - Route map while you run - Keeps coaching with the screen locked AFTER THE RUN - Heart rate chart, time in zones, route map and splits - Trends: MAF pace, aerobic decoupling, weekly Zone 2 minutes and training load - Route heat map of where you run - Field tests for resting HR, max HR, HRV and CO2 tolerance YOUR DATA STAYS YOURS No account, no server, no sync, no AI, no ads, no tracking, no subscription. Runs are stored on your device. The only optional lookups are weather and elevation for a run, and you can turn them off in Settings. OPEN SOURCE BaseMile is free software under the GNU GPL v3 or later. The full source code is at https://github.com/likwiid/basemile BaseMile needs a Bluetooth heart rate chest strap that uses the standard Heart Rate profile. Without one it still tracks pace, distance and route. For the lifting days, pair it with PlateClimb from the same team. BaseMile is not a medical device and is not medical advice.
