Awful
The principle is good but the execution very poor. The alarms are hugely irritating. The repeat function does not correspond to menu settings (i.e. instead of reminding every 30 or 60 minutes - as set - the app continues to alarm annoyingly every 5 minutes without break). The functionality is weak. But its a start.
