Ive been using this app for about 4-5 years now. Its a really nice app to measure your sleep time and to see your sleeping behaviour. I personally dont use the feature to wake me up when the phone thinks Im the least asleep but its definitely a good feature! The thing that makes me only give 4 stars is that they barely update the app. There has been a recent update but before that it has been years. Another thing is that since I got the app they have the ambient noises to fall asleep in development but they didnt add any new ones or changed anything about it so it would have been nice to also include that more into the app. In conclusion this is a good app though and it does what its supposed to do very good!
