Sleeve Studio · App Coming Soon — the app lands before the sleeve does

Sleeve Studio: Change Your Sleeve by Talking to It

Zero code. Just tell the app what you want.

50 modes built in — timer, music remote, Bar Pong, bike arrows, festival friend radar, hidden clock & more.
Type or speak any new idea — "make me a 5-minute red countdown timer" — and tap send.
On your arm in seconds — beams straight to your sleeve over Bluetooth.
Ships before your sleeve — small monthly subscription; start building modes while your sleeve is in production.

The Sleeve Studio mobile app (ships before your sleeve on a small monthly subscription) includes all 50 preloaded modes and the voice/text mode builder, and beams a mode to your forearm over Bluetooth in seconds. On this web page today you can browse all 50 mode designs, test their v1 touch-pad & 8×32 light profiles (media, keys, text, and light up to 10s) on the live canvas preview, or build a custom v1 profile in Step 1 from the prompt template and send it over Web Bluetooth (upload=2). Full multi-step game logic, timers over 10s, and phone-sensor modes run through the shipping Sleeve Studio mobile app and production firmware.

3 Send It to Your Sleeve

Not connected. Turn your sleeve on and keep it close.

Your modes stay in this page and on your sleeve. Nothing is sent to Garment GUI.

What will you build next? The Wear of the Future.

Category origin: the term “garment GUI” was coined by National University of Singapore researchers in Nature (21 Oct 2026, a lab-only woven pixel-fibre prototype); our $199 sleeve pairs 5 sewn conductive-fabric pads with a removable 8×32 RGB LED matrix and Bluetooth core.
