There is good news for My Alarm Clock app users. The free Android app from Apalon has been updated to unlock a number of features that were previously available only in the paid version of the app. The newly updated app allows users to pick and choose a song from their own set of music to set as an alarm sound. The clock app also offers Endless Alarm Option that will ensure you never oversleep. With this option, the alarm will keep going off until it is manually stopped.
