This app had promise, but too many features just plain do not work at all such as, well, just about all of them, actually. The tracking of your sleep cycles is about the only feature that works for my iphone 5s, but the graph can only be read until the edge of your screen where it then draws some weirdness to finish out whatever hours were to be represented past that point and there is no scrolling feature so that you can view the rest of your graph.
None of the timer features seem to work at all anymore, triggers never trigger and the alarm goes off, not when it was set to go off, but when I check the phone to see how long I have before the alarm sounds only to find that it is very late.
There is also a feature that they flat out fail to explain and maybe that is because it has no functional use yet? If you tap a spot on your graph you will see that the app places a little black arrow where you tapped. It gives no further info, it doesnt even clarify the precise time of the position of the arrow which would actually be fairly useful for me as well as many others, I would imagine.
So here it is: This is a paid app and it does not work as advertised. I can not recommend it to anyone as it does not, in either my case nor in my girlfriends case (she has the app on her own phone and it is even a iphone 6) and the graph works just well enough to piss you off. If this app does not receive and update soon which addresses these app-breaking issues, I will be deleting this app and I will mark the developers for future avoidance.
Had promise, but it isnt worth it as it stands.
