WAKE UP ON TIME: Proper Alarm Settings
• Keep the app open and running always to have your alarm go off and play the sounds you’ve set for ‘Music'.
When your app is open, you can use the volume slider within the app. When the app is in the background, use the device volume to set your volume.
• Make sure your battery is charged and have your notifications turned on before you go to sleep, when the battery level goes below 30% it might not sound. This is due to prevent the device from dying and the alarm not going off.
• Keep your Apple Music available on your device
The music you can select consists of everything you have available on your ‘Apple Music' app on your device. If the music is saved on your iCloud, and not on the device itself, it won’t be available.
NEVER MISS AN ALARM
When you close the app and do not have it running in the background, the alarm will use the device volume instead and play the notification sound system.
The app will close itself automatically after 10 hours of inactivity. This is due to prevent the device from dying and the alarm not going off.
When your device is muted, set to ‘Do Not Disturb’, or your device volume is set to 0, the alarm won’t play properly. It will still show the notification without any sound. This is due to Apple’s restrictions as we are unable to access the app settings when the app is closed, only when it’s open or running in the background.
