The Xs Alarm Clock - Fully restore your normal life rhythm with sufficient sleep, which will be controlled by your new alarm clock! Even if you set your phone to silent mode, "Do Not Disturb" or airplane mode, you will still hear the melody at the chosen time. Choose your own music for the alarm, apply the crescendo effect for a smooth increase in volume, set mathematical tasks for a more challenging alarm deactivation, and switch between themes to enjoy changing settings.
