Once Upon Aclock
Alarm to prevent being late
Only for iPhone
$1.99
iPhone
Aclock gives you a random head start to help you stop being late.
Set the time you actually need to be ready by. Aclock may ring early by a random amount, while its on-screen clock gradually moves ahead so you can’t easily predict how much extra time you’ve gained.
The amount changes each time, so there’s no fixed pattern to rely on.
Choose how much help you want:
- Standard — Rings once.
- Ring Again — Rings a second time.
- Wake Check — After the second ring, Aclock keeps checking until you confirm you’re awake.
When the alarm is finished, Aclock reveals exactly how much time you gained — down to the millisecond.
For alarms set within 20 minutes, Aclock stays on time. For longer alarms, it may move up to 20 minutes ahead.
Leave Aclock open while it’s running to keep the screen awake and use its shifted time as your clock.
Aclock. A better lie than your excuse.
