GridCall

"Hey, when is my next session?" GridCall answers that question all weekend long. Live schedules, session countdowns, and paddock info for race weekends — heats, scrutineering — published once by the organizer and updated on your phone the second they change. No group-chat scrolling, no photographed timetables.

Follow your weekend from one app: pick your category, and GridCall keeps a countdown to your next session on your phone, your Wear OS watch, and your home-screen widget. Offline-first by design — a bad paddock signal never costs you the plan. GridCall is the partner app of Rotax Max Challenge Switzerland and Rotax Max Challenge Italy.

WHAT YOU GET
• My Watch — one glance: what's on track NOW and a live countdown to YOUR next session, anchored to the assembly-gate time, not just the green flag.
• Full schedule — every heat, quali and final for every category, with gate-open and start times, breaks and podium.
• Session reminders — exact alarms at 30, 15, 10, 5 and 1 minute before your sessions.
• Home-screen widget — the countdown without opening the app.
• Wear OS — countdown, sessions and paddock activities on your wrist, with a tile and last-seconds haptics.
• Paddock activities — registration, briefing, tyre collection: on the panel, checked off as they pass.
• Demo weekends built in — try the whole app today, no account needed.

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.
