About

Dokkaebi is an arrival alert app for iPhone and Apple Watch that vibrates and notifies you when you get close to a spot you picked on the map. The spot does not have to be a station or a stop, and you choose an alert radius between 100 m and 2 km.

It is free on the App Store and shows a banner ad at the bottom of the screen. A one-time in-app purchase removes ads and unlocks limited features. Requires iOS 26.2 or later.
