I need to track cardio with terrain data, but I’d rather not trust Strava with my privacy. I know there are some alternatives, but which one is the most reliable and feature-rich? I don’t have smart accessories, just and android phone. Preferably, I’d like an app that let’s me track added weights for calorie purposes (like rucking).
Runner Up, on f-droid is great for measuring speed and the like. I assume you meant running and gps. Other sports (e.g. gym, weights or functional training) got other apps. I’m not logging anything, just use TimeR Machine for everything. As for the food, I have no experience but there are a couple of apps on F-droid like FitBook or SECUSO’s food-tracker. Good luck!
