This free tool allows users to automatically check attendance and verify the recovery time of in-game resources, such as Resin and Trailblaze Power. The add-on works seamlessly in the background, checking for web check-ins when the browser is active.

Hoyoverse Check-in supports multiple games, including Genshin Impact, Honkai: Star Rail, and Honkai 3D. Users can register multiple accounts for a single game, making it convenient for players with multiple game accounts.
