Works very well
Great app, it work well on my phone, I have a iPhone 6+, and on my phone it shows how long I take to fall asleep, my light sleep and my deep sleep and when I woke up, it tell you how long you spent in light sleep and in deep sleep and the total amount of time you have slept, again great app, and with the adds it only show at the bottom of my screen, that is the least to me, not a problem.
