Simple and clean
I appreciate it app. It just runs a timer and sounds the bell (or gives haptic feedback if the bell is silenced) at the end of the meditation. The meditation is then saved to the health app/data, along with a heart rate reading. Having this on my watch as a complication encourages me to do some meditation when time allows. Apart from 1 minute, the meditation periods are in increments of 5 minutes. For the most part that works for me. Occasionally I would appreciate being able to set custom times.
