The little screen on your lanyard.

It clips onto your keys and shows your next lecture, records voice notes and rings your alarms.

Pre-orders are closed.

The full launch is next. Join the waitlist and I'll email you as soon as it opens.

Curious? Try it in your browser ↗. It runs the real firmware.

    Agent

    Hold B on the home screen and say what you want: a timer, a new event, an app, or what's next. It asks first before it changes a setting, deletes a reminder or turns off every alarm.

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.

Write your own apps

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.

Each app runs in a sandbox with its own memory, its own folder and a time limit. 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, or start in the editor on the tools site.

  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.
