Sleep cycle analysis

Track sleep duration and quality, and explore daily, weekly, and monthly reports without a separate wearable device.

Night sound recording

Sleepster helps record snoring, sleep talking, and other night sounds so you can better understand what happens during the night.

Sleep sounds

Choose calm, pleasant soundscapes to relax before bedtime, unwind, and create a softer evening routine.

Smart alarm

Set your wake-up so the app can help you wake during a more suitable moment of light sleep — on time and feeling refreshed.

Clear reports on sleep and morning well-being

Sleepster helps you do more than record the night — it helps you notice recurring patterns: when you fall asleep, how long you sleep, whether you wake up during the night, and which habits may affect your morning mood.
