Sleep Cycle
The ultimate sleeping app
About the app
Sleep Cycle is an alarm clock app that tracks your sleeping patterns with your microphone, and then chooses an optimal time (within a 30 minute period) to wake you up.
I would recommend this app to anyone who has trouble waking up from their alarm, or find that when they wake up they feel like they were interrupted during their sleep.
Interface
It has a nicely designed interface that is easy on the eyes, especially when your first waking up in the morning. It also has a good choice of relaxing alarm tones, which help you wake up with ease and comfort.
Pros/Cons
Pros
The alarm wakes you up at just the right time, so you are awake and ready for the day.
Cons
It is free on Apple app store, but on the Samsung play store it costs $0.99.
