Cons
Con Alarms no longer sound when using Android 10
Alarms will trigger but sound is disabled under Android 10's new silent notifications section. App needs an update to support this, and it's been stagnant since 2017.
Con Pricey at $3.99
Con Have to manually tell it when you go to sleep
This doesn't work as seamlessly as sleep trackers in wearables, like Fitbit trackers. It doesn't record your sleep time, you have input when you go to sleep and when you wake up, which makes it far less useful.
Con Requires outside file viewer to wake up to music
In order to choose a song on the SD card, a file viewer is required.
