Sleep Cycle analyzes your sleep patterns and wakes you in the lightest sleep phase – a natural way to wake up where you feel rested and relaxed.

5/5 Stars on
“Sleep Cycle Alarm Clock is $0.99 and you would be insane to not go and buy this app right now. It just works. Period. It does exactly what it advertises which is absolutely amazing.”

What our users are saying:
“I was baffled at how well it worked. Almost every day I used it, I felt refreshed when the alarm started.” – Christina Karlsson

“Waking up at the right time is an amazing thing. I couldn’t believe the difference it made!” – Michael Palka

“It felt like I was already awake and the iPhone just let me know it.” – Anders Hejdenberg


Sleep Cycle monitors your movement during sleep using the extremely sensitive accelerometer in your iPhone. Sleep Cycle then finds the optimal time to wake you up during a 30 minute window that ends at your set alarm time.

Look at the screenshots for recommended iPhone placement.


Sleep Cycle was developed using proven sleep science and five months of exhaustive testing.

As you sleep you go through different phases that range from deep sleep to light sleep. The phase you are in when your alarm clock goes off is a critical factor regarding how tired you will feel when you wake up.

Since you move differently in bed during the different phases, Sleep Cycle uses the accelerometer in your iPhone to monitor your movement to determine which sleep phase you are in.

Sleep Cycle then wakes you in your lightest sleep phase.

Remember! Do NOT lock your phone when going to bed. Sleep Cycle automatically shuts down your screen and puts the phone into a power saving mode. If you lock your phone Sleep Cycle will not sense your movement and will then only be able to wake you at the end of the alarm time.
