Vetkuro

Vetkuro is lap timer and track day telemetry app for drivers who want more than just a time. Sector splits, telemetry overlays, GPS racing line and OBD-II channel logging - all working from the phone in your pocket, with the gear you already own.

Whether you run track days at your local circuit, compete in karting, autocross or time attack, or just want to understand why your lap times aren't improving, Vetkuro gives you the data layer that makes the difference.

GPS LAP TIMER & SECTOR TIMES
Vetkuro starts timing the moment you cross the start/finish line. Each lap is split into sectors so you can see not just your total time but where you are gaining and losing against your best. Compare sector-by-sector across unlimited laps and sessions. [Assumption — verify lap comparison limit]

TELEMETRY THAT MAKES SENSE
Unlike basic lap timer apps that give you a number and nothing else, Vetkuro logs full telemetry channels: speed, braking, throttle, G-force and heart rate. Overlay them lap-over-lap. Find your braking point. Find your exit speed. Find the tenth you have been leaving on the table.

GPS RACING LINE
Your GPS racing line is plotted on a track map after every session. See where you braked too early, where you ran wide on exit, where your line through sector 2 cost you. Data, not guesswork.

OBD-II ENGINE DATA
Connect a compatible OBD-II adapter and Vetkuro logs engine channels alongside your GPS data. Supported adapters: Carista, vLinker MC+, NEXAS NexLink.

HEART RATE MONITORING
Pair any Bluetooth LE heart-rate strap or your Apple Watch and your BPM is recorded alongside speed, GPS and OBD channels. Track your physical response to on-track stress.

HARDWARE SUPPORT
Vetkuro is designed to work without any add-ons, your phone's GPS is enough to get started. When you want higher accuracy, pair it with supported external hardware.

BUILT FOR EVERY TRACK DISCIPLINE
Track days. Karting. Autocross. Time attack. Club racing. Vetkuro works at any circuit where you can define a start/finish line.
