Very nice :)

Feedback: mostly I need to do this at work currently, which means I am going to retreat to a quiet place and grab my phone.

Phone Screens going to sleep and the thing being interrupted by tapping anywhere on the screen are not compatible. Not sure if other people face this issue, but for me tapping anywhere on the screen in order to not make the phone go to sleep should not interrupt or restart this meditation. A small X in a corner would be better.

Nit: The scrolling on your site is horrible broken on mobile. Keeps rubber banding and bouncing around.
