Meditime is the simplest meditation timer available. Swipe up or down to set the timer – set it to zero, and it’ll run as a stopwatch – and double-tap to start. When you’re done, Meditime will automatically log the session to the Health app. And that’s it; no muss or fuss, just doing what you want it to. And it was built with privacy in mind; your data is your data, and we dont send any of it anywhere.
(Mindful minutes only get logged on devices that have the Health app; other than that, Meditime works fine on any device running iOS 12 or later.)
