Worked for a while, then it wouldn't stop buzzing unless I closed the app.
It's nice because it can just be put on vibrate. Doesn't wake others. You can just put under your pillow. No other app offers this.
An essential must have app for deaf or vision impared people! I have a hard time waking up without my wake n shake alarm, and one day it broke. Until it was fixed, I found this app and It works brilliantly! Set the time to go off and and vibrates forever until turned off - it even vibrates when the screen is off! The only thing missing is the ability to schedule multiple and repeat alarms. Even without this feature, it is still a must have for deaf people!
Pointless anyway as every android phone has a vibrate only alarm.
This app is so simple to use and works so well. It's been what I've been looking for and it's a well presented app.
