Okoshite · Alarm
Next stop is yours: Kasumigaseki
Why Okoshite?
No GPS underground?
You still won't oversleep.
Apps that rely on location alone stop working when the subway takes away GPS. Okoshite keeps going underground.
GPS-only apps
Underground they lose track of where you are, so the alert comes late or never. And a notification is easy to miss on Silent.
Okoshite
Tracks your trip above ground and in the subway, and sets a backup alarm for your expected arrival. Every one of them is an alarm that rings on Silent.
How it works
Pick, close, rest.
Pick your station
Type a station name, in English or Japanese, and choose your line. Where you boarded is filled in from your location.
Close the app and rest
Okoshite keeps working with the screen off. No signal needed, no data used.
Woken one stop before
“Next stop is yours” wakes you up, and “This is your stop” gets you off on time.
Features
Everything it takes to wake you up.
Rings on Silent
A real alarm built on AlarmKit in iOS 26. It rings on the lock screen and through Focus.
Backup alarm
A second alarm is set automatically just after your expected arrival, just in case.
~10,000 stations
JR, private railways and subways across Japan, built in. Station names in English and Japanese, with Tokyo Metro line colors.
Rapid and express trains
On trains that skip stations, just set the number of stops. Above ground it also uses GPS.
Works offline
Everything runs on your iPhone. No connection needed in tunnels or underground.
Screenshots
Clear at a glance, even half asleep.

FAQ
Good questions, answered.
Does it work in the subway?
Yes. Okoshite keeps track of your trip underground, where GPS can't reach, including Tokyo Metro and Toei Subway lines.
Does it ring when my iPhone is on Silent?
Yes. It uses AlarmKit in iOS 26, so it rings through Silent mode and Focus, just like the Clock app's alarms.
Does it work offline?
Yes. The station data is built into the app, and everything runs on your iPhone.
Does it work on rapid and express trains?
Yes. On trains that skip stations, set the number of stops to your station. Above ground it also uses GPS.
Does it drain the battery?
It only works while you ride and stops by itself a few minutes after you arrive.
How much does it cost?
Every alarm feature is free. Okoshite Plus, which saves unlimited favorite routes, is a one-time purchase, not a subscription.
Is there an Android version?
Not yet. Okoshite is for iPhone (iOS 26 or later).
Is the app in English?
Yes. The app is in English and Japanese and follows your iPhone's language. Stations can be searched in either.
No more waking up at the end of the line.
