KERB: Formula Circuit Guide

Race-week schedules, session alerts and a corner-by-corner guide to all 27 circuits on the 2026 calendar and beyond.

KERB turns every Grand Prix circuit into something you can actually read.

Tap any corner to see how it's driven — where to brake, which gear, the line through it and what to watch for. Hit play and follow a full lap as the car flows through every sector, with each section explained as it happens.

FOR FANS • Race-week schedule in your local time, with a countdown to the next session • Session alerts before practice, qualifying, sprint and the race • Results and championship standings that update after every race • Home screen and Lock Screen widgets • Lap records, circuit character and a built-in glossary of racing terms

FOR SIM RACERS • Corner-by-corner braking, gear, line and throttle notes • Sector, overtaking and detection-zone layers on every map • Straight Mode and Overtake Mode zones for the new active-aero era

ALWAYS UP TO DATE Track data, active-aero zones and lap records update automatically during the season — no app update needed.
