Zen Timer

Zen Timer is a distraction-free meditation app with no ads, no popups
and no unnecessary features. Just a beautiful timer that helps you
maintain a regular meditation practice.

Spin the zen circle to set your duration, a singing bowl chimes 3 times
to start, another chime ends it. Sessions get logged automatically with
a calendar heatmap so you can watch your practice build up over time.
This feature can also be disabled if you just want the timer.
