TRACK Dash · second screen

A spare phone becomes your race dash.

Mount a second device where you can glance at it and TRACK Dash shows what matters at speed: delta, lap and sector times, shift lights and warnings. It runs its own layouts, not a mirror of the recording phone.

04TRACK Dash · second screen

A second iPhone becomes your HUD.

Not screen mirroring. Your spare iPhone or iPad runs its own dashboard, in its own layout and units, from an encrypted link to the phone that’s recording. It works without internet.

Numeric comparison

A 6-digit code on both screens, confirmed on the recording phone. Nobody nearby can slip in.

Encrypted end to end

X25519 key agreement, ChaCha20-Poly1305 frames, counter nonces and replay rejection.

Resumes on its own

If the link drops, it reconnects without re-pairing. Stale data is flagged, never frozen silently.

No internet needed

Local Wi-Fi or peer-to-peer, so it works in a paddock with no signal.

Does it need Wi-Fi at the track?

No. The two devices can connect peer-to-peer.

Android?

An Android phone or tablet as the dash is planned with the Android app.
