For teams and scuderias
Every crew in your team, prepared the same way
Every crew trains with real timing before the event, drives with the same clear screen on the day and looks honestly at every trial afterwards, so the whole team arrives prepared, not just its best crew.
It counts: at the 1000 Miglia, a sponsor team is scored on the sum of its best three crews.
Train. Race. Analyse.
One app for the whole season, from the first practice run to the last classification.

Illustration Arrive trained
Practise timed trials before the event, against real road sensors or with the phone alone. Every pass is timed and kept.
How it works: Train02 · Race

The whole day on one screen in the car: countdown beeps to drive by, seconds early or late on average-speed trials, and taps from the navigator’s remote.
How it works: Race03 · Analyse

Every run kept. Your taps next to the official times, driver and navigator apart, and the trend month by month.

Made for a phone on the dash
Big numbers, few words and colour that carries the message, so a glance is enough at speed.
Training, pass after pass
A countdown with beeps to the tube, then each pass lands in the Last pass card: driver and navigator, early or late.
Illustration
Average-speed trial
On target, or how many seconds early or late, with the distances and speed beneath.
Illustration
After the event
Every trial with its points, the driver’s and the navigator’s share, and the trend over the season.

GPS hardware
Built for RaceBox GPS hardware
Crono107 works with the RaceBox Mini, Mini S and Micro. Pair one and Crono107 reads distance and speed from its 25 Hz satellite receiver instead of the phone. It connects from Chrome on Android today, and if it drops out during a run, the phone’s GPS takes over by itself.
- 20 cmprecision, with RaceBox
- 25 Hzposition readings every second
- Autoswitch to the phone’s GPS if it drops
