    2017: Compelled to update bc this has gotten worse due to the bait and switch ad tactics. Good luck getting to the main screen to set this. If you are willing to launch and app, click through 2-3 screens AND then figure out how to extract yourself from the never ending ad campaign with no escape good luck. Good app function if you can get to it. Incredibly poor user interaction snd monetization. Go find something, anything else. The shenanigans are not worth it. Your standard alarm on your phone is enough to wake you up. Any other sleep app that 'measures' sleep stages has the be less of a hassle than this. Too bad they can't figure it out. 2016: The functions of this app are good but the last update has made it ridiculous to set. I was considering purchasing the premium version for the storage but not after the last update. Now they want you to log in or buy the premium version. If you can locate the button to skip this process among the clutter them you get served up a completely irrelevant ad. You then have to wait for the ad to finish (which it sometimes never does) to click out of it. If you can't click out and attempt to close the app and reopen it it usually crashes at least once before you can attempt the whole process again. I've been using the app for a year but am looking for a new one because of the nonsense. There are other sleep app options with less in your face unrelated advertising and no ridiculous logins.

    I used and loved this app for over a year because it was simple to use and it woke me in the morning with bird sounds. I did not need or want all the frills like the heart monitor and the exercise stuff but they did not interfere with the alarm clock so I ignored them. Then I made the mistake or updating. Now I can't use the morning birds without paying them. I can't set the clock without watching ads. And I can't use it to track my sleep without giving them personal information that can be used to identify me in a future health database. AlI I wanted was an alarm clock, not Big Brother. Sad, sad, sad.

    I've used this app for 8 nights and I love it but on the fourth night it has asked me both times if I like the app (yes) and rate it, the first time I said no, the app the proceeded to prevent me from changing the alarm. Then tonight it asked me it again (yes, and yes I would rate it). I tried changing the clock after my first review and it still wouldn't let me. The only solution was to uninstall it and reinstall it which loses all the saved data. Please fix this bug and it would be 5 stars (maybe 4.5 because the ads playing insanely loud at 1am is not fun.)
