The No.1 Health and Fitness app in Japan!

Sleep Meister is an alarm application that sets pleasantly timed alarms using a device's built-in accelerometer to sense body motion and sound an alarm when the user is in a light stage of sleep (REM sleep).
It can also be used with HealthKit, and comes with a wide variety of functions, such as automatic tweets while sleeping, recording sleep talking (sounds), a snooze function to stop the user from falling asleep after waking up, and a music player that automatically stops when the user falls asleep.

Changed the way I awaken!

Love waking up to this this app! Use every morning as my alarm... Never thought I would be able to awaken with just a gentle bit of "cool" music riff but what a difference compared to being screamed and buzzed at by the typical alarm! On occasion I use to look at sleep quality data but the alarm at my bedside for me is amazing!


Best app ever.


I am obsessed with this app. It wakes you soft and sweet when you are in a deep sleep and wakes you up boldly when it knows you are stirring. It's incredibly accurate when you are awakened and will show on the graph. It's incredibly accurate when you're in a deep sleep and displays as such on the graph. Provides the % of sleep efficiency. You can choose any song from your music. It wakes you in the range of your wake time not always the exact wake time. Snooze is available of course for those times. Bottom line it wakes you sweetly when you're in a deep sleep not so lightly when you are stirring. How does it know?
