This app is brilliant for getting a general overview of your sleeping habits... Mine are terrible as it turns out... But knowing this has motivated me to sorting it out! The free version works for me, the only downside is the lack of alarm tones that you would otherwise get if you paid. Great app overall though.
I still love the time when it worked for me. Lovely app. However, for the recent year or so, it almost always wakes me up 30 minutes before the set alarm time, regardless of the sleep phase I'm in. I wrote the developer about the issue. They were helpless. I use a Samsung Galaxy Note 5. Not sure if I'm the only one suffering from this pathetic failure. I don't rate it 1 because of the earlier days when it worked.
Under normal circumstances I would give this app a 5 star rating. However, after updating my OS and the app, it has stopped generating reports correctly. Upon ringing one time, it will spit out an error saying something along the lines of "failed to generate report." When I check the report, it will record sleep efficiency as 1% and the graph will show that i was awake the whole time. Additionally, the snooze function ends up shutting the alarm off completely because it is unable to track my sleep cycle. This has been happening for a week now and I've only ever had this problem before with a much older version if this app on android 4.0.
How about I finish signing up before you throw ads and your "premium" in my face? I hate Apps that are obviously just trying to make a buck out of everything.
My alarm glitched out a few times now and wouldn't ring. When I opened the app, the numbers at the bottom disappeared.
Used to set a backup just in case, but this alarm works well. Generally find I wake up feeling more awake than usual, so I think it is working.
