Amazing This app... Gosh its amazing. Life changing man. Being a student I usually mess up my sleep cycles. Now I can get back on track whenever and its so simple and I always feel refreshed (as I can be when I wake up xD)
Good but no perfect This appis great calculating time to sleep and wake up .it is connected with alarm clocks on your phone to set the alarm. The only con i can see is in the want to sleep now mode, which also needs a nap function and not only 8 hours sleep.
Life Changer This app has literally changed my life! I used to wake up sleepy and/ or late almost everyday. I thought I needed more sleep but it was just impractical for me to go to bed that early. With sleep cycles, I go to bed at a reasonable time and wake up refreshed. I get to work on time and I feel great! The UI is not that attractive & I wish I could choose the alarm. That's why I gave it 4 stars instead of 5.
Unpredictable at best After using the " going to sleep now" button and selecting what time I should wake up, it sometimes works perfectly, but sometimes adds 12 hours to my alarm time. I can't see any kind of pattern and it's quite frustrating to wake up late, then have an alarm go off that evening telling you to wake up...
For one day.... The app worked great the first time I used it, and I woke up refreshed. Tried to set it tonight, but the wake up times never changed, no matter what time I set for when I was going to bed. Removing app, can't have something working only when it wants
Works better than expected I was skeptical at the concept, but it really seems to work. Have woken up fresh quite a few times now. Great app
Version 4 removed ads. Version 3 crash was due to ads being removed.
Version 5 will include a built-in alarm. I am currently in the process of creating and testing this alarm. This should help the Galaxy S2 users who cannot access their alarm in Android 2.2, 2.3, and 4.0.3.
