I put my AI agent on my Apple Watch, and it runs on my own computer

Last week I was across the room when my AI agent stopped and asked me a yes/no question. It needed permission to run a command. My laptop was 20 feet away.

That's when I decided the approval prompt belonged on my wrist.

Flash is the AI assistant I run locally. It's got chats, background agents called sparks, and team chats where those sparks talk to each other. Flash for Apple Watch puts all of it on your wrist.

It's open source: https://github.com/Natuworkguy/flash-watch

The watch talks to Flash running on your own computer. There's no hosted backend and no account. Pairing uses an address plus a six-digit code that works once, for five minutes.

Wi-Fi only gets you so far. The moment you leave the house, a watch that can only see your home network is just a watch.

So there's a Reach from anywhere button, in the watch's Settings and under Watch in Flash. Tap it and:

Tunnel addresses change, and that used to mean retyping them. Now the watch asks Flash for its current addresses every minute, so a new tunnel address just shows up. Your agent can ask for approval from a coffee shop, and you can answer from your wrist.

Your computer still has to be on and running Flash. The tunnel is a way to reach it, not a place your data moves to.

You'll need Flash on your computer, plus a Mac with Xcode 16 or later to put the app on your watch. A free Apple ID works.

/extension install github@Natuworkguy/flash-watch Enter fullscreen mode Exit fullscreen mode Let the watch reach Flash. Run flash --web --lan (or /web lan ), or turn on the public link in Settings. Put your team in watch/Local.xcconfig: DEVELOPMENT_TEAM = ABCDE12345 FLASH_BUNDLE_ID = com.yourname.flash Enter fullscreen mode Exit fullscreen mode With your watch on its charger and unlocked, run: scripts/watch.sh install Enter fullscreen mode Exit fullscreen mode Open Watch in Flash's sidebar, then type the address and code on your watch.

Away from home? Tap Reach from anywhere in the watch's Settings. Why a watch?

Agents are getting more autonomous, and the human in the loop is now the bottleneck. A yes/no approval should take two seconds, not a walk back to your desk. The wrist is the one screen that's always with you.

Clone it, break it, and tell me what's missing. Issues and PRs are welcome.
