A simple meditation timer I can hit in the app, so I don't need another app or to leave the app. I use the Apple Watch a lot it's built in meditation timer maxes at 5 min so if I go above that, I need to use the timers app (which requires numerous taps) or download a meditation app which has too many features.

For extra credit:

1) Make the timer have an "approximate" or "maximum" option - so that it will stop at some random time that is approximately or within a threshold of the amount of time selected or that is less than the maximum amount of time selected. A lot of people meditate without a timer to just get a natural "my body knows how long it needs" experienceThis is so that your body doesn't get used to meditating for a specific amount of time and can essentially learn to just wait out the clock - while still giving you some control if you need to keep a schedule. A lot of people meditate without a timer to just get a natural "my body knows how long it needs" experience, but that can be difficult if you're busy, but this parameter would allow the best of both worlds.

I actually don't know of a meditation app that does this (though I'm sure one exists), so it would be a really cool and unique feature.

2) Could have simple mediation sounds like singing bowl, waterfall, forrest, brown noise, etc.
