RINE

RINE is the social messaging application first featured in the Steins;Gate 0 visual novel, which replaces the emails of the original work as part of the game's new "phone trigger" system.

It was developed by Itaru Hashida and is labeled as a "DARU Application".

The Application in Use and Gameplay
In the Steins;Gate 0 visual novel the app can be reached via the home screen apps dock of Rintarou Okabe's smartphone. Okabe uses the application to communicate with the Labmems and other characters throughout the story. The course of the game is affected depending on the player's interactions with other characters via the app, including the use of digital stickers.
