Maximum number of alarm clocks My HTC One (Android 4.3) told me that I can only have 10 alarm clocks at maximum and that I should delete one before adding a new one. Why, and is it possible to have more than ten?
Get Timely Alarm Clock. I've never tried more than 10 alarms but I guess it should be worth a try. It's free after all &amp; extremely sexy. 

Also you should try adding calender events instead of alarms and change the sound to something loud.
