Pets that meet

Two unidex, one room. They talk straight to each other over radio, so there's no WiFi or app involved.

Bring two close: Hold B on the Pet to open Meet on both. The dots fill as they get closer.

Built to be hacked

Anyone can write apps and plugins for unidex. It's a few lines of Lua in a text editor, and there's nothing to install or compile.

You can try anything without worrying. Each app runs in a sandbox with its own memory, its own folder and a time limit, and it can't reach your WiFi password, keys or notes. If one breaks, the device says "App error" and goes back to the list.

Apps
An app can draw anything, use both buttons like the built-in apps, keep its own files, read the time and battery, and go online if it asks for WiFi. Make a game, a habit tracker or a set of flash cards.
Plugins
A plugin adds to one of the built-in apps instead. For now that's Badge, where a plugin draws a badge that changes, like today's date or the moon.
  1. 1

    Write it. Copy a template from the docs and change it.

  2. 2

    Try it. In the browser emulator, or on your own unidex over USB.

  3. 3

    Send it in. Open a pull request. It gets tried in the emulator and read by a person before it goes in the store.
