One Alarm is a minimal alarm clock.

Drag the minute hand to set the alarm time. Drag or tap the switches to turn the alarm ON/OFF and quickly set AM/PM.

If you’re sick of complicated alarm interfaces, One Alarm is for you. Tapping through multiple menus just to set an alarm is tedious. With One Alarm, you can set an alarm with one tap.

Simply set the alarm and exit the app. A badge on the One Alarm icon will appear and countdown every hour to show approximately how many hours are left until the alarm sounds.

We hope you like it!

Love, CW&T

It works. (my bad)

Come to find out the alarm didn't work, unbeknownst to me: my lack of the iPhone new setting features. Make sure your Notifications are intact.
CW&T offers great customer support. They walked me thru my issue. This alarm is clean. Minimal. And extremely samurai!

I really like this ultra simple alarm app VERY much! It works perfectly and I can easily set the alarm within just a few seconds. The best part is that this alarm ALWAYS works. It has never failed me.

It is truly the epitome of simplicity!!!
