About Speed Lab →What the app does
Setup management, session logging, and AI tuning, designed for the way you actually work at the track.
Setup Management
Create, save, and share detailed kart setups with your teammates. Load a saved setup straight into a session so you stop flipping through a notebook trying to remember what you ran last time.
Session Tracking with Live Weather
Log every session at the track. Real-time weather (temp, humidity, pressure, wind) is captured automatically so you can correlate setup changes against actual conditions later.
KART AI Tuning Assistant
Ask KART AI for setup recommendations from the pits. It looks at your kart, your session, and your conditions and gives you a starting point. Built on top of the same AI that powers Speed Lab coaching.
Voice to Text
Talk to your phone while gloves are still on. Dictate session notes hands-free so you actually capture what you noticed, not just what you remembered to write down later.
Mychron & Alfano Session Data
Pull session summary data straight from your Mychron or Alfano so your lap times and key channels show up alongside your setup. No retyping.
Trends & Session Compare
Stack sessions side-by-side to see what changed when you changed the kart. Track how a setup evolves across conditions and over the season.
Built for the kart hauler, not the laptop.
How it fits into your day
Before the session
Load a setup
Pull up your saved baseline for this track or this kart, tweak what you want to try, and you have a setup sheet ready when the kart goes on the stand.
During the session
Log it, weather and all
Record the session as you run it. Weather is pulled automatically from your location, so you do not need to remember to write it down.
Between heats
Ask KART AI
Wondering what to change? Ask KART AI in the pits. It sees your kart, your session, your weather, and gives you a tuning recommendation you can run with.
After the weekend
