COMPARISON
Phone app vs dedicated hardware. The right call depends on how serious your data needs to be.
RaceChrono
£15
Mobile app for GPS lap timing using phone sensors. Supports external Bluetooth GPS receivers.
RaceBox
£199
25 Hz GPS + IMU logger with Bluetooth app, designed for amateur racers.
RaceChrono Pro is a one-off £15 app. RaceBox Mini is £199 of hardware on top of your phone.
RaceBox's dedicated u-blox receiver samples at 25 Hz with sub-metre accuracy. Phone GPS rarely beats 10 Hz and drifts more in tunnels and pit areas.
RaceBox has a dedicated IMU. Phone IMUs work via RaceChrono but are noisier and reset when the phone screen sleeps.
RaceBox is designed to sit on the bike, take rain, and survive a small off. Phone mounts fail more often than people admit.
RaceChrono is install-and-go. RaceBox needs pairing, a quick calibration, and somewhere to mount it.
RaceBox runs an 8-hour session on its own battery. Phone sessions chew through 50%+ in an hour and overheat in direct sun.
Use RaceChrono Pro for casual track days when you're just curious about lap times. Step up to a RaceBox Mini the moment you start caring about lean angle, repeatable accuracy, or comparing laps session-to-session. Both export clean data — both pair with ApexIngest.
ApexIngest natively imports RaceChrono CSV and RaceBox CSV. If you already have RaceChrono and want corner coaching, lean angle visualisation, and lap overlays, you don't need new hardware — you just need ApexIngest at £9/month.
From £9/month. Works with RaceBox, AiM, MoTeC, Starlane, RaceChrono, and more. Join the waitlist for early access.
