LapSnap now supports recording your laps using just your phone. - Visualize the lines and analyze each lap to see why you’ve been fast or slow in a particular part of the track. You can analyze speed, acceleration or deceleration, gas and brakes application, RPMs, gear change, lean angel for motorcycles, temperatures for Go-Karts, as well as your line on the map. - Compare your laps with your best lap, optimal lap or with someone else’s lap to see what you can do to become faster. - Easy access to each session and each lap. This way you can always refer back to a particular lap. - Leaderboard. See how you stack up against others racers. Each track has a leaderboard. - Save your setup. Every session can contain your vehicle settings like suspension setup, gear ratio, tires you use etc. This way when you're coming back to a track, you can refer to the settings you've used the last time and you're not wasting valuable track time finding a setting that works. - Optimal Lap. Your laps are divided into sectors. By taking best sectors of different laps we can put together an Optimal lap. This way you can see what you are capable of if you get every part of you lap just right.

Karting Days

Karting Days turns a day at the track into a debrief you can actually act on. Write your setup down trackside like you always have, then photograph the sheet. The app reads your handwriting into real fields. Add your MyChron data, pick the laps that count, and get back a report that shows where the time is and what to change before the next session. TWO WAYS IN Scan a handwritten setup sheet, or log the day by hand with no camera at all. Every later scan that day merges into the same sheet instead of starting a new one, and you can pull forward your last setup at that track instead of starting from blank. YOU SEE WHAT GETS ANALYZED Every analysis starts on a review screen: which sessions, which files, which laps. Drop the out lap, drop the one where you got held up, then confirm. Nothing is ever submitted blind. A REPORT, NOT A WALL OF TEXT Best lap, theoretical best, consistency, and where the easy time is sitting, up front. Under that, a corner scorecard ranking the corners costing you most, sector and corner charts that name their own baselines, and a breakdown of what your setup changes actually did. The full written analysis is one tap down if you want to read it. EVERY REPORT ENDS WITH A NEXT STEP A target lap for the next session and a short list of changes worth making, as a checklist you tick off at the track. Tell it how the kart actually felt and the next report weighs that against what the data measured. Ask a follow-up question and the answer stays attached to the report. WATCH THE LAP BACK Play back any lap on a track map colored by speed, or switch to load to see grip instead. A dot tracks your position while speed, RPM, lateral G, and elapsed time update beside it, all synced to a scrubbable speed and RPM strip. Corner notes from the report appear on the map, right where they happened. SEE HOW YOU STACK UP Import another driver's data file and find out where they are actually quicker. Lap and sector deltas, corner by corner, one racing line colored for who held the edge, plus a ghost race you can watch. Their data stays walled off in its own report and never touches your bests. The same tools work on you: any two days at a track side by side, and your best-lap trend over the season. WHEN YOU DON'T KNOW WHAT TO CHANGE Pick what the kart is doing, pushing on entry, loose on exit, won't rotate, hopping under braking, and get fixes ranked in the order to try them. Every fix links to a plain explanation of what that adjustment actually does. The troubleshooter and the reference guide under it work with no signal at all. ALSO INCLUDED Conditions filled in automatically for every session. Real track maps matched to your sessions by GPS, with numbered corners. Read-only event links for a coach or teammate, approved person by person. A web dashboard once your iPhone is paired. NO ACCOUNTS, EVER No email, no password, no signup. Your phone is the account. Works with .xrk and .xrz files plus Race Studio .csv exports, covering MyChron 5 and 6. SUBSCRIPTION Your first 2 AI session analyses are free, no card required. After that, Karting Days is $29 per month for 10 analyses a month, every feature included, no tiers. Need more mid-month, add 5 analyses for $12 anytime. Payment is charged to your Apple Account. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period, and you can manage or cancel in your App Store account settings.
