Nice app and open source, seems great if you don’t need guided meditations want a no-nonsense app. If you want a guided open source meditation app, try medito, though the unguided experience is less customizable there. Personally, for keeping tracks of streaks independently of the meditation app, I use the open source Loop Habit app, where I also track other habits. But if you don’t need to record other habits, I guess the built-in recording of an app is more convenient.
