I like the chime feature when I'm leading a meditation session. However it's a strange app to use when you want to time your own meditation. First of all it doesn't sound the chime when your time is up. How would you know that 5 mins have passed when your eyes are closed and you're meditating? You get a notification on your phone but no sound. Second, it doesn't work when your phone is on dnd. I tried it on dnd and the (no audio) notification just appears. If not on dnd your Apple watch just buzzes. But who would meditate without putting their phone on dnd first? Very strange app.
