Group intercom for riders.
Full duplex. Online or offline. Ready before you ride.
Connecting multiple intercoms together is a pain.
You have a Bluetooth helmet. Your riding buddies do too. But mix brands and it falls apart: failed pairing, mono audio, groups capped at two or three, and five minutes of setup before you even hit the road.
Dedicated intercoms do the job well — as long as everyone has the same one. On the road, that's rarely the case.
But there's one device every rider already has in their pocket.
Your phone becomes the group intercom.
HelmSync uses the phone you already own and the Bluetooth helmet you already wear. No extra hardware, no complex cross-device pairing. Each group member installs the app, joins the session, and group communication starts — in seconds.
Online mode
High-fidelity real-time voice infrastructure. Full duplex audio between all group members, wherever you are.
Offline mode
Local network automatically activates when mobile signal is absent. The ride goes on.
Simple. Before you even start.
Create or join
The leader creates a session, others scan the QR code or enter the 6-digit code. That's it.
Open communication
Voice is transmitted in real time to all members. Full duplex: everyone can talk and hear simultaneously.
Group visible on map
GPS positions of members are displayed live on the map. You always know where every rider is.
Zero configuration
The app switches automatically between online and offline mode based on available network. No action needed.

Mountain passes, dead zones, tunnels — offline mode takes over automatically.
An independent project. A real product.
HelmSync is built by a rider, for riders. Not by a funded startup looking to monetize your data.
The app is free in its entirety. Communication features are not locked behind tiers or premium levels. Optional support tiers are available if you want to back the project.
The code is solid. The architecture is built on cutting-edge real-time protocols deployed on a controlled infrastructure.
PIT-TO-PILOT RADIO. WITHOUT THE $1000 HARDWARE.
Professional radio systems cost a fortune and require complex licenses. Forget walkie-talkies that crackle at the end of the straight.
HelmSync turns your smartphone into a real racing radio. A phone in the driver's suit, the pit crew with their own earbuds, and you get clear, real-time "Pit-to-Pilot" communication. Pro performance, finally accessible to everyone.
Zero setup
No UHF frequencies to scan, the group is ready in 10 seconds.
Unlimited range
The link stays perfect anywhere on the track, as long as the phones have internet (4G/5G).
Consumer hardware
You already have the hardware in your pocket. Use any smartphone.
Coming soon.
HelmSync is in beta. Real-world testing is underway. Store release is approaching.
