Bunker: Ark APK for Android

Bunker: Ark, by Matvei Kavtorov, is an Android companion that translates the social deduction board game Bunker into a device-driven session manager. The app removes administrative friction so players concentrate on debate, persuasion, and voting, while the tool handles hidden roles and session pacing. It supports offline synchronized play, a large expandable card library, and an end-of-game narrative generator. Fans of Mafia-style deduction and owners of the physical Bunker game are the primary audience for this assistant-style app.

The app acts as a digital facilitator for live social-deduction sessions

This tool focuses on the social loop of hidden information, argument, and voting rather than presenting a solo video-game experience. It produces secret character attributes such as professions, health traits, baggage, and phobias and sets environmental conditions that affect discussion. Sessions accommodate four to nineteen participants, so it suits tight groups and large parties. The app can function as a standalone manager for characters and scenarios, not strictly as a remote control for the box.

Synchronization and round management remove manual bookkeeping from play

Synchronization uses an arithmetic-based, serverless method: an eight-character "One Code for Everyone" lets multiple devices share the same setup without a central server or continuous internet connection. The app also includes practical timing tools, including a speech timer and a round counter, which keep debate moving and make it easier to enforce time-limited turns during meetings and parties. These elements aim to standardize session rhythm across groups.

Content volume and narrative closure keep sessions fresh and consequential

The card library scales from roughly 1,300 free cards to as many as 2,500 with expansions, which increases variation across sessions and supports different playstyles. The Ark expansion adds a generated "Survival Story" that narrates the group's outcome based on survivors and choices, providing a deterministic finale. The breadth of cards and the interactive ending mean repeat sessions change key social dynamics rather than repeating the same scripts.

Platform reach and intended players shape practical suitability

The app targets Android devices running version 5.0 and up, which defines the technical audience and keeps it focused on mobile tabletop groups. It is created by an independent developer who specializes in digital board-game companions, so players who already enjoy party deduction games such as Mafia or Werewolf and owners of the Bunker board will find the design aligned to their needs. Cross-platform tabletop play outside Android is not part of the featured setup.

A practical companion for in-person deduction players, with a single-platform limitation

Bunker: Ark is a practical choice for groups that prefer debate-led sessions and want a device to handle setup and pacing, particularly people who run games for larger numbers of players. The principal constraint is platform reach, since the app is available for Android only, which matters if some participants use other ecosystems. For Android tabletop groups, it provides a tidy way to reduce prep and add a narrative finish.
