ShutEye recognizes, calculates, and analyzes the files recorded by the microphone through artificial intelligence algorithms to produce your sleep status information.
At the same time, selected sleep recordings, such as snoring, are available for your listening and sharing.

Through the artificial intelligence algorithm, ShutEye will look for the lightest stage of sleep between the wake-up phases you set, and will sound the alarm at this time to gently wake you up and make you wake up more easily.

One reason for the discrepancy might be that the app records time spent asleep, not time in bed. Taking this into account, if you still feel Sleep Tracker has shut off prematurely, this might be caused by insufficient phone charges. Please be sure that your phone is plugged in while using Sleep Tracker.

Please keep the charger connected. Put down and lock your device.
