Most customizable

There are several apps to measure and visualize sleep data. I tested five, and this one not only provides most of what the other all together can offer (besides statistics: notes, dream record, snooze, export, sound to fall asleep and wake up) but customizing options the other seldom, or none, have: sensitivity, data visualization, sounds, lists, etc. I value that a lot.

And for free, the ads arent obtrusive. It is the only difference with the paid version, so it is totally functional, not like some not usable lite versions of others. This developer seems to have a more subtle and long term strategy of inviting you to like and buy his app, avoiding to force you into frustration like some colleagues.

Its for me the best option, I truly recommend it.
