How it works

You ask. We build. You wear it.

Ask for a single feature or an entire face. Our agent builds it and you get a fresh build on your wrist in minutes. No limit to fresh builds. Ask again until it is exactly right.

  1. 1Ask in plain words
  2. 2Our agent writes the build
  3. 3A fresh build lands on your wrist

Morning run. Pace, distance and my heart-rate zone. Nothing else.

Built. Pace big, distance under it, zone as a ring. Fresh build sent.

When I wake up, show my sleep score. Then just the time for the rest of the day.

Done. Score for ten minutes after you get up, then it goes quiet.

Next three hours of weather and my first meeting.

Built. Three columns of weather, your first meeting underneath. Calendar stays on your phone.

Quiet hours after nine in the evening. Except my mum.

Set. Quiet from 21:00 to 07:00. One exception: Mum.

Flight day. Gate and a countdown to boarding.

Built. Gate big, boarding countdown under it. It drops off the face once you are seated.

Suggested templateRun · Day · Night. One face that switches itself. Accept or ignore.

Accept.

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

Privacy

Five promises, kept by design.

  • 1

    We do not control your watch.

    No remote kill switch. Nothing is pushed. You ask, we build, you decide.

  • 2

    We do not want to know you.

    Asks are anonymized before they reach us. No telemetry leaves the watch.

  • 3

    Health data stays with you.

    Heart rate, sleep and temperature live on the watch and your phone. Not with us.

  • 4

    If we disappear, it keeps working.

    The five essentials and every build you already have stay on the watch.

  • 5

    It is yours to open.

    Firmware is open source, compiled per user and published to your account. Flash it yourself over USB.

Questions

Short answers.

Do I need the agent to use the watch?

No. Time, date, steps, heart rate and temperature work without an account, app or subscription. The agent is for everything else, and every watch comes with two free builds.

What happens when I ask for something?

Our agent writes the firmware for that feature or face, compiles it for your watch and sends a fresh build to your phone. It lands on your wrist in minutes. Ask again until it is exactly right.

Does the agent see my data?

No. Asks are anonymized. The understanding of how you use the watch is built on your phone and stays there. Health data never leaves the watch and phone.

Can I flash the firmware myself?

Yes. Each build is open source and published to your account. Connect over USB and flash it.

Are the hardware specs final?

They are targets. Titanium, sapphire, a 1.3" memory-in-pixel display and up to 14 days of battery are what we are building toward. We will say clearly if anything changes.

How do I pay?

Dollars or crypto: USDC, BTC or ETH. Pre-orders are refundable. Checkout opens soon; until then write to hello@rvrs.ai.
