ps: for a backend think about collecting meditation statistics, and pulling in meditator networking, online meditation groups, running longitudinal meditation studies "how was your sit" and other parameters... if you eont put that into the meditation app you want the meditation app to send notifications to the other apps, so add events and notifications to the no-backend list above.
point being: its more than a timer and notifications.
