"Hey, when is my next session?" GridCall answers that question all weekend long. Live schedules, session countdowns, and paddock info for racing weekends, from heats to scrutineering, published once by the organizer and updated on your phone the second they change. No group-chat scrolling, no photographed timetables. Follow the Rotax Max Challenge Switzerland and Rotax Max Challenge Italy weekends from one app: pick your category, and GridCall keeps a countdown to your next session on your iPhone, your Apple Watch, your Lock Screen, and your home-screen widget. Offline-first by design — a bad paddock signal never costs you the plan. GridCall is built for everyone at the track: drivers who need the next call, mechanics planning the stint, and families who just want to know when to be at the fence. Race series and event organizers can run GridCall in their own colors — visit gridcall.ch to see it in action. GridCall® is a registered trademark.
