5/5Great app!
A few things that would improve it greatly: 1) Most important for me would be the ability to change the alarm time mid-session without turning the alarm off! I find it very useful to plan my sleep in multiples of 45 minutes, so if I wake up and by the time I go back to sleep there’s only 30’ left, it would help to be able to add another 15’ or even an hour! 2) It would be nice to be able to edit-say double tap or tap and hold an area on the chart and correct it-like when i forget to tutn it off. There coild be something diff colors) that shows it was edited to preserve integrity. 3) Also if I go back to bed so there are 2 separate sessions for the same night it would be great if they would display stacked. Thanks for a super app!

1/5Not worth our money
I get up several times a night to use the restroom and this app doesn't recognize or record truly when I'm awake I wasted my money on this app and I want a refund. It doesn't track right. Therefore you shouldn't be charging for this app. It also wakes me up an hour before My alarm is set to go off. I would really like to see an Apple Watch app added to this app. It would help your sleep time++ work better. I spoke to one guy through your Argus that uses a fit bit. So I ran a little test of my own. I put my Apple Watch on its charger in evening to give it a full charge before my bed time and there was orange at the time I got up for a nature call. But it still doesn't turn orange at the end when the alarm goes off to wake me, indicating when I'm awake. Bottom line, this still needs a lot of work. Suggestion: how about adding a sound recording feature. So people can learn if they talk in their sleep or snore or have apnea. This app is not worth the money. you lie in the diagram. it's never been accurate. I wasted my money. And when I messaged through facebook you just gave me the run around.

5/5Best sleep alarm ever
I’ve used this app for around seven years now and it’s the only alarm that I’ll wake up to. I love it because it starts low and gradually gets louder. I hate being woken up by typical alarms that just go right off at full volume. I’ve used this app with the phone laying on my bed (as it suggests for the best reading) and ok my night stand. When on my bed I can accurately tell when I move or wake up or when I’m still and sound asleep. It’s very accurate. I’ve since moved to placing it on my night stand instead because I no longer need to see all the extra data. Instead I now only use it as an alarm and sleep time tracker (to see how long I sleep each night). This is my favorite sleep app and I doubt I’ll ever use another one.

5/5Works great!!
I read previous reviews of this application, and I do not agree. The application does not assess what is going on for you during your sleep cycle. That part is up to you. All the app does is to provide you with the necessary information so that you can assess your sleeping patterns, cycle and how you feel in the morning. With that being said, the application delivers everything that the publisher states it will. I would recommend this to anyone who wishes to assess their sleep cycles as to maybe why in the morning they wake up, and they don't feel all that well. Or they wake up and they feel great, and this way they can reassess what and how well they slept so that they can get another great night of sleep. Worth every penny.

5/5Better sleep how many stars do that?
I read a few reviews and from what I gathered there were bad reviews they were rebutting. I stopped reading. I'm not going to waste my time reading negatives about a great program. Frankly I don't care what it does for anyone else as long as there are enough happy users to keep them in business. I wake up refreshed no matter how little or how much time I have to sleep. I can't explain how the system works, but it does. Not once in awhile, but every time. Don't be fooled by buffoons who have another mission. Good sleep combined with nutrition and exercise is more valuable than the vast majority seems to realize. Earl Brown
