What VIO does

Your WHOOP has no screen. It measures your heart rate around the clock and sends all of it to your phone, which is what you want for the rest of the day.

While you run, that leaves you without the two numbers that steer the session: your heart rate, and the pace you are actually holding. VIO shows both. It reads the heart rate your WHOOP broadcasts and marks the zone you are in. With its own GPS receiver it tracks your pace and route.

VIO with a built-in battery, a short USB-C cable and a short printed guide.

Which WHOOP does it work with?

WHOOP 5.0 and WHOOP MG. You switch heart rate broadcasting on once in the WHOOP app, and VIO listens in.

When will it arrive?

Dispatched within one business day. Three to five working days inside the EU, tracked, and you get the tracking number by email.

Can I send it back?

Yes. Run with it for thirty days. If it is not for you, write to info@vio-run.com within thirty days of delivery and we reply with a return label. Send VIO back complete and undamaged, and the full price goes back to your payment method within ten working days of arrival.

Is there a warranty?

Yes, a one-year limited warranty. Michael Klotz (sole proprietorship), Via Bolzano 45, frazione Frangarto, 39057 Appiano sulla Strada del Vino (BZ), Italy, warrants to the original buyer that VIO is free from defects in materials and workmanship for one year from the day of delivery. If it fails in that time, write to info@vio-run.com with your order number and what happened. We send a return label and repair or replace it at our cost, or refund the price if no replacement is available. Not covered: normal wear, the gradual loss of battery capacity, damage from accidents, misuse or modification, and failures caused by changes to third-party services such as the WHOOP heart rate broadcast or Strava. This limited warranty gives you specific legal rights, and you may also have other rights which vary from state to state. Consumers in the European Union also have the statutory two-year guarantee of conformity.

I love my WHOOP, but having a second watch bothered me always, so I ran without knowing my pace or heart rate. Now with VIO I have a seamless device and the data in one place.

FAQ

Questions

Where does the heart rate come from?

From your WHOOP. VIO has no sensor of its own against your skin. It only shows what your band already measures.

Do I need my phone while running?

No. Pace, distance and recording happen on the device. You need a phone or a computer afterwards, for setup and for uploading.

Where do my runs end up?

After your run is finished, connect your phone and upload it to Strava. If set up correctly, all the data shows up in your WHOOP app.

How long does the battery last?

12 hours of recording time on a full charge.

Is it waterproof?

Yes, VIO is waterproof, IP68.

Why not just wear a running watch?

If you want a running watch, buy a running watch. It does more and you can have it today. VIO is for people who want to keep the heart rate source they already wear and still see two numbers, without a second watch.
