Okimasu - Wake Up Grid Alarm
Won't stop until you clear 25
$1.99 · Designed for iPad. Not verified for macOS.
The alarm that makes 5 more minutes physically impossible. Tap 1 to 25 in order or it keeps blasting. Wear earphones and the blast is yours alone - your family sleeps on.
Okimasu is a blast alarm built for one thing only: making sure you actually wake up.
You set one thing: the time. Press START and go to sleep.
■ There is only one way to stop it
When the alarm fires, tap the 25 tiles on screen in order, from 1 to 25.
The blast keeps ringing until every tile is cleared.
One wrong tap and you start over from 1.
A half-asleep brain cannot clear it. By the time you do, you are awake.
■ No snooze
"Five more minutes" does not exist here. Wake up, or it keeps ringing.
■ Blast in your earphones only
If earphones are connected when the alarm fires, the sound plays only in your earphones. Your family or partner in the same room stays asleep.
Pull them out mid-blast? It instantly switches to the speaker and keeps ringing. There is no escape.
■ Nothing you don't need
- No multiple alarms
- No weekday repeats
- No sound packs
- No ads
Set the time. Press START. That's it.
■ How to wake up reliably
After pressing START, keep the app open and plugged in. The screen dims automatically.
If you close the app, notifications will ring the alarm instead.
