Works without signalPitch & rollRollover detection
02 · Approach

From everywhere.
To the same pass.

Turin, Pinerolo, Susa, Briançon: RUDX shows live who is where – until everyone stands at the Colle delle Finestre.

03 · Meeting point

Air down.
Press start.

First waypoint: lower the tyre pressure. One tap on “Start – I'm driving” and the convoy rolls onto the track.

04 · Assietta

Gravel, ridge, 2,400 m.
Before you see it.

Low range 4L, rear locker, washed-out rut – planned hints arrive exactly at the spot. Pitch and roll always in view, with your vehicle's limits.

05 · Photo stop

Colle dell'Assietta.
Time for a stop.

Photo stop, ford, recovery point or camp: the organiser plans waypoints ahead. Everyone stops at the same place – RUDX announces it in time.

06 · No signal

No signal.
Radio keeps going.

There is no reception on the ridge. The iPhones form a chain and pass radio, positions, hazards and SOS from car to car.

07 · Arrival

Sestriere.
All together.

38 km of track, 1,213 m of climbing, six cars. Air up – nobody lost.

08 · Recap

The whole trail.
To relive.

Route, elevation, pitch, roll and heart rate in your recap – and the next expedition is already planned.

Offroad waypoints

When it gets hard

Low range, lockers, recovery – all on board.

Off the beaten track, what counts is that everyone knows what to do. RUDX plans the drivetrain, calls for help and guides you through the recovery – even without signal.

Questions

Frequently asked questions

Picture guide →

Does RUDX work without cell signal?

Yes. The iPhones in the convoy connect directly (Bluetooth and Wi-Fi) and pass on radio, positions, hazards and SOS. With signal, everything also runs through our server in Switzerland.

Do I have to operate anything while driving?

As little as possible: one big talk button, RUDX announces everything else. On the Apple Watch there’s nothing to press – it only vibrates when it matters.

Who can see where I am?

Only your group and only during the tour. Inside your home zone no position is sent at all.

What happens in a crash?

RUDX detects strong impacts and rollovers, starts a countdown and alerts your crew with your position. You place the emergency call yourself – RUDX shows you the right number for the country you are in.

Which devices does RUDX run on?

iPhone (iOS 17 or later) with the Apple Watch as a companion. Android is planned.

Which languages are available?

The app and website are available in German, English, French, Italian and Spanish – including all voice announcements. More languages will follow.

How much does RUDX cost?

Riding along is free, and the safety features always are. Premium starts at CHF 34 a year, Organiser at CHF 79 – each for road or offroad, both together for less. At launch, every feature is free.

Is this allowed while driving?

You don't need to operate anything at the wheel: announcements come by themselves, and you talk with one big button, the steering-wheel or headset button, or your Apple Watch. The iPhone belongs in a mount – like a sat nav.

How much battery and data does RUDX use?

About as much as a navigation app with radio. You download maps per tour in advance over Wi-Fi. On long tours, keep the iPhone on a charger.

Does RUDX work with CarPlay?

Not yet – RUDX runs on the iPhone in its mount and on the Apple Watch. CarPlay is on our list for later.

What if not everyone has RUDX?

Riding along is free – an invitation by code or link is all it takes. Anyone without RUDX isn't visible in the convoy and doesn't hear the radio.
