Rockstar Games will release a companion app for Red Dead Redemption 2 on Oct. 26, the same day the full game hits stores, that will deliver “real-time interactive information” to Android and iOS devices.

The Red Dead Redemption 2 app will let players view the game’s world map, and set waypoints and mark areas of interest as they explore, according to a post on Rockstar Games’ website. The app also promises real-time information on Arthur Morgan’s health, stamina and other stats, which Rockstar says will aid players who prefer a HUD-less game presentation.
