## Description

minimalist alarm

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

One Alarm is praised for its ultra-simple, single-purpose design and quick setup, with many reviewers noting it reliably triggers alarms. The minimalist interface earns praise for a clutter-free experience. However, a recurring concern is that alarm reliability can hinge on iPhone notification settings, and misconfigured notifications may prevent the alarm from ringing. The interface’s simplicity can also make it easy to forget to turn the alarm on or to doubt that it’s set. Overall, it’s a clean, dependable alarm when notifications are configured correctly.
