One brand, two pieces

Start on the phone. Carry it to the table.

Relic Companion stands on its own as an offline dice app. Relic Die is the physical M5Stack Core2 prototype it can program over Bluetooth. You do not need the hardware to understand—or enjoy—the companion experience.

M5Stack Core2 · prototype

Relic Die

A tabletop hardware experiment built around the M5Stack Core2. The prototype receives game profiles and short sound clips over Bluetooth, then keeps them so the table can play after the phone disconnects.

  • Compatible firmware remains in active prototyping
  • Profiles and sounds are stored on the connected die
  • Designed for standalone play after setup
  • Not a finished retail product and not shipping
Prototype means prototype.

Try the table before the test.

This browser build mirrors the real companion flow: choose a themed table, roll dice, adjust counters, enter Advanced, and connect a simulated M5Stack. It is a product demonstration—not a Play Store installation.

How the journey works

Roll now. Program later.

The app is useful on its own. Hardware adds a second place for the same rules and sounds to live; it is not a prerequisite.

Choose a table

Enter Dragon Keep for high-roll d20 attacks or Case Files for low-roll percentile checks. Switch dice without leaving the table.

Shape the rules

Set targets, bonuses, critical and fumble bands, or the hard and extreme success divisors that fit your game.

Send a profile

Use the simulated die now. With compatible prototype firmware, send the selected rules and clips directly to a connected Relic Die over Bluetooth.

Closed-test field notes

Follow the release without pretending it has shipped.

The next public milestone is a real Google Play closed-test listing. Until that exists, the browser demo, policy and support pages are the authoritative web experience.
