Five things, built in. Nothing to sign up for.

The watch does these on day one, offline, with no account, no app and no subscription. They are the baseline the agent builds on.

02how it worksask → build → wrist · no limit on fresh builds

You describe it. Our agent compiles it. It arrives.

STEP 1AskIn the phone app, one sentence. A feature or a whole face. Plain words, no settings screens.
STEP 2BuildOur agent compiles firmware for your watch, signs it and publishes it to your account. The source is open.
STEP 3WearA fresh build reaches the watch over Bluetooth in minutes. Not right yet? Ask again. There is no limit.

templates Once our agent understands how you use the watch, it suggests templates: several features combined into one face. That understanding is built on your phone and stays there. Accept or ignore.

What we cannot see.

Not "do not". Cannot. The data never reaches us, and the firmware that could send it does not exist.

07faqshort answers

Does it work without the agent?

Yes. Time, date, steps, heart rate and temperature are built in. The two free builds are yours as well. Everything you already have keeps running if you never subscribe.

What happens to builds if I cancel?

They stay on the watch and in your account. You can reflash any of them over USB. You lose the ability to ask for new ones until you subscribe again.

How long does a fresh build take?

Minutes. Compile, sign, transfer over Bluetooth LE. Complex faces take longer than single features. Ask again as often as you like.

Is the firmware really open?

Yes. Open source, compiled per user, and each build is published to your account. You can read it, change it and flash it yourself.

Are the hardware numbers final?

No. Case, glass, display, battery and sensors are targets. We will publish measured figures from the first production run before any pre-order becomes final.

Which phone do I need?

The app runs on iOS and Android and talks to the watch over Bluetooth LE. The understanding our agent builds of your day lives in that app, on that phone.

Can I pay in crypto?

Yes. USDC, BTC or ETH, alongside dollars. Checkout opens with the first production run; until then write to hello@rvrs.ai.
