Hey OP, can you share how you came across this company? It is incredibly new, the domain has only been registered for a few weeks, and their are barely any google results for it.
Captrice works in a browser on an android phone. But honestly, it's designed to be used on a desktop/laptop with a keyboard as there are some handy keybindings/shortcuts for easily controlling the metronome while playing the instrument.
If you are specifically looking for an android app, I've only found one that comes closest - Instrumentive[1]. It allows tracking time for the entire practice session besides uploaded recording of the session. Whereas my use case is to track the duration of practice at every tempo. Trying to play for extended duration seems to work well for me in terms of building endurance and muscle memory.
