## What is One 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

### 1/5 — Circadian Rhythm Needed

*2023-09-28, version 2.5*

Because the minimalist design alarm did not work. For some reason it worked yesterday afternoon. No explanation for multiple notifications that can’t be accessed in any way I could figure out. Most reviews are years old.  Maybe too minimalist.

### 5/5 — Perfect!

*2020-10-25, version 2.5*

The only alarm app that's just that...an alarm! Love it!

### 4/5 — This is what it’s all about.

*2020-10-09, version 2.5*

Love this app so much. Thank you!

### 4/5 — ✔️ 👍🏼  // Needs some options added / updated

*2020-05-29, version 2.5*

Love the simplicity just would like to add alternate alarm sounds.

### 3/5 — Getting better

*2017-10-09, version 2.5*

I love the simple design and ease of setting. 
It’s just an alarm. Period. Hard to screw up. The devotees still need to work on iPad compatibility and when a decide rotates the screen is really messed up. Let’s get these bugs worked out!

### 5/5 — Perfect!

*2014-10-11, version 1.23*

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!!!

### 5/5 — minimal, to the point.

*2013-06-21, version 1.23*

Excellent design, simple and initiative. Great app.

### 3/5 — Less is More

*2012-06-29, version 1.23*

This app is not 'Free' as one has to pay $0.99 after 10 days of use. However, as described One Alarm is minimal and it is simple. This also makes it very convenient and quick to set and use. So simple and easy that one is more likely to use it as a timer or short term reminder than as a traditional alarm clock. With this use in mind (timer/reminder) it could do with a couple of improvements:

- Show current time using hands in different colour or 'ghost'. With this it would be easy to set the alarm time a specific amount of time ahead of existing time.
- In conjunction with the above it would be useful to have a button to 'set to current time'. This would save one having to wind the hands round to the the current time period when setting it up as a short term timer (kitchen timer for example).
- Needs to show time remaining to alarm time or, as mentioned above, show actual time with hands in different colour so that one can visually determine time remaining.

With some minor improvements this app might actually be useful and worth buying and deserve a higher star rating.

### 5/5 — Great

*2012-06-14, version 1.23*

CW & T always make top notch stuff. Great app!

### 5/5 — Tom McCarthy

Well worth the cost.
