MyChron RT app for iPhone and iPad
With AiM MyChron4 RT you can download your data at the end of the session with rental karts.
When you race in tracks equipped with MyChron4 RT karts, keep your mobile on hand: at the end of your session on its display a QR-Code will appear, which you will read with the app.
So you will have your data stored, compare your best laps and share with your friends!
