NilgiriIM is an iPhone and iPad app (iOS/iPadOS 17 or later) that lets you play Nilgiri from your phone like a chat app.
While your character is parked, you get push notifications for tells, whispers, prayers, the start of combat, death, and link loss. Each notification shows your character's name in its title.
Only one character can be parked per device: the latest one to enter the game.
Every login stops at the main menu.
The app doesn't use telnet. It connects over HTTPS to the Nilgiri IM server at https://nilgiri.net/im, which keeps your game session alive and sends the push notifications.
NilgiriIM is not on the App Store yet. It's coming to TestFlight.
Source code and issue reports: Nilgiri-IM-Client on GitHub. If you're not sure whether a problem is in the app or the game itself, open an issue there anyway and it will get routed to the right place.
