How it works

Three taps between sessions. Every lap after it.

Each step is the real app, recorded start to finish. Watch it, and you know how to use it.

01

Set up the day

Name the event, pick the track, add your driver and their kart with a goal for the day - and the first session is ready to go.

02

Capture after every run

Tap how confidence, turn-in, mid-corner and exit felt, say it in their words, and log what you changed. Done before the next session is called.

03

See what worked

Put two sessions side by side - lap time, ratings, notes and setup - with every difference picked out in orange.

Recorded in the app with its demo data; the drivers are made up.

Features

Everything you used to write on the back of a tyre sheet.

Quick driver feedback

Tap a rating for confidence, turn-in, mid-corner and exit, then say what they felt - the keyboard mic works too.

Setup change tracking

Before and after for every adjustment, with the last value filled in for you. Nothing forgotten at the end of a long day.

Tyres and weather

Cold and hot pressures for all four corners, with track temperature and conditions - so you know what to start on next time.

Back at a track?

See what you ran there last time: setup, pressures, weather and what the driver said.

Compare and report

Sessions side by side, trends across a weekend, and a one-tap PDF report to send to the driver and the family.

Works with no signal

Everything is on the phone, so it works in any paddock. Add Cloud to have it on your PC before the kart is off the trailer.
