As one of the earlier testers, I can say I was astonished by the 2.0 changes. Tracking sleep is one of the most important 'trackings' in my repertoire and Sleepagotchi is probably the best choice available
I am used to daily routines but adopting a tool for describing, tracking and adjusting them is a game changer.
Routinery seems to be the best option for iOS!
I am still not sure whether having habits and pomodoros (I use Pomo for specific recurring activities) in the same app where todos are, however, TickTick got me, a seasoned productivity geek and a project manager, to a whole new level of control.
Facing some minor bugs, however, this app has solved my major browsing-related pains I've had in Chrome (I needed spaces to separate inbox, personal and work stuff).
