Get Simple Beeper old version APK for Android
Beeps at set intervals.
The app can be set to beep continuously at any set interval. It can also be configured to have a beep of different tone for every 'x' number of beeps. The existing apps on the play store were not the easiest to use and hence this app was born. This can be used for any of your requirements such as for a metronome, Yoga( suryanamaskara) or any exercise etc..
