Sleep as Android is an alarm clock that analyzes sleep using the smartphone’s built-in sensors. It requires you to set a wake-up time, enable sleep tracking, and place the phone next to the bed. The app records the user’s movements in bed and displays the corresponding sleep phases in a report. Sleep as Android is also compatible with most smart watches and bracelets.

The app records sound during sleep to track snoring and sleep conversations. Lullabies help you fall asleep to different melodies. Also, for a soft wake-up, the sound of the alarm clock increases gradually, and the melody is played during the rapid sleep phase. At the same time, the developers recommend that the phone is connected to a charger, as various modes of operation can lead to a complete discharge of the battery.

The app contains a host of customizable settings that allow you to set your preferred sleep and wake-up settings, interaction with wrist accessories, and backup.

The app is free and ad-free. However, cycle tracking features and integration with wrist accessories are available in a 2-week trial period. To unlock it, you must purchase the PRO version of the app for 7.5 USD.
