Tell the app how your kart behaves through a corner and it tells you what to change on the chassis. No guessing, no forums, no depending on somebody in the pit having a good day. HOW IT WORKS You pick the symptom — understeer, oversteer, hopping, sliding on all four — where it happens (corner entry or exit) and how strongly you feel it. The app crosses that with your pressures, your temperatures and the conditions of the day, and gives you a list of adjustments ordered by priority: where to start, what is worth trying and what to do if it persists. Every piece of advice comes with its explanation and its illustrations. It is not a black box: you can see why it suggests each thing. COLD TARGET PRESSURE The rest of the app analyses what you already measured. This screen answers the opposite question: what do I set cold BEFORE going out so the session ends inside the tyre's window. It accounts for the compound, air and track temperature, track condition, grip and total weight, and shows you the breakdown of what moved the number. 31 compounds from MG, Bridgestone, Vega, LeCont, MOJO, Maxxis, Evinco, Komet and Hoosier, plus generics by hardness for when yours is not listed. THE NOTEBOOK It saves every session with its pressures, temperatures, conditions, tyre and the advice you were given. Add the laps and your best time: it is the only thing that really tells you whether the setup worked. With two or three sessions saved you can already compare. You can keep several karts. And share a whole session as an image, ready to send over WhatsApp, which is what already happens in every pit. CATALOGUES 142 circuits from 24 countries, with length, layout type and abrasiveness. 33 chassis models from 11 manufacturers. And if yours is not there, you type it in and it is saved all the same. CALCULATORS Gear ratio, with the theoretical top speed of each combination and how much one sprocket tooth moves things compared to one on the rear. And air density, to know how far today is from the day the engine ran perfectly. MEASURED YOUR WAY PSI or bar, Celsius or Fahrenheit, kilos or pounds. You switch from the screen itself and whatever you already measured is converted. HELP ON EVERY SCREEN Every screen has its own help, written by someone who has taken tyre temperatures in a paddock: how you actually measure, what mistakes people make and what each number means. HONEST ABOUT ITS DATA The pressure windows come from tuner guides, distributors and the specialist press. When a figure is not confirmed, the app says so. It does not sell you certainty it does not have. One-off purchase. No subscription, no ads, no account. Works with no signal, which is how most paddocks are.
