Sentinels Sidekick is an Android application designed to streamline gameplay for Sentinels of the Multiverse enthusiasts. This full-version app replaces traditional tracking methods with a digital companion that manages hit points for heroes, villains, minions, and environment cards. Players can easily adjust hit points, track turn effects, and apply ongoing buffs or boosts with just a few taps, making it an invaluable tool for both new and experienced players.

The app supports all characters and environments from the base game and its expansions, featuring high-resolution artwork for an immersive experience. Players can utilize a custom effects keyboard, flip villain cards automatically, and access rules and discussions directly within the app. Although it does not include the OblivAeon Event game mode, Sentinels Sidekick offers a comprehensive solution for managing gameplay, allowing players to focus on strategy rather than logistics.
