Best Karting Apps UK: Which App Does Which Job

Search for karting apps and you get a jumble. Booking apps, lap timers, apps that need a dash on your steering wheel, apps that need nothing but your phone. They're all "karting apps", and they barely overlap.

So decide first what job you want the app to do. Once you know that, the choice gets easy. We've split them into four jobs below, with one table to compare them and a straight answer on which ones are free.

We make one of the apps on this list (Race Ninja, the video-analysis row), so we've kept to what each product says on its own site or store listing, checked on 26 October 2026. Prices change, so check before you buy.

What are the best karting apps in the UK?

It depends on the job. Here's every app in this guide in one table.

Which karting app is for booking and live timing?

If you mostly drive hire karts, the most useful app is probably the one your track runs. These aren't analysis tools. They're how you book a session and see your times afterwards.

TeamSport Karting UK is TeamSport's own app for its UK tracks. It has in-app booking, an online race licence, live timings with driver leaderboards and your previous race details. It's free on both the App Store and Google Play. If TeamSport is your local, get it.

RaceFacer and Pixelcom are a bit different. They make the timing and booking software that venues run, and the driver apps show your results at whichever tracks use them. RaceFacer's driver profiles carry your results and lap times. Pixelcom's app shows sessions and podiums for each track plus live timing, keeps your personal records and gives you a QR code licence to show at the track. Whether either one is any use to you depends entirely on whether your track runs it.

What none of these do is tell you why you were slower than your mate. For that you need one of the next three jobs.

What's the best phone lap timer for karting?

A phone lap timer uses the phone's GPS to time your laps and sectors. Strap the phone to the kart (or put it in a pocket, if the app allows it) and you've got a lap timer for the price of an app.

RaceChrono says it has over 100,000 active users, and you'll spot it in plenty of paddocks. On Android there's a free version, and RaceChrono Pro costs £19.99 on the App Store and £18.99 on Google Play. Pro adds video recording and data overlays, and it can link and sync video from most action cameras. It also works with external GPS receivers, which matters more than people think (more on that in a second).

Harry's LapTimer has been around for years and runs on iOS and Android in three editions. On the UK App Store Rookie is £8.99 and Grand Prix is £29.99, with Petrolhead in between at £19.99, and video overlays start at Petrolhead. It's written with car drivers in mind but times a kart just as happily.

LapTrophy is free to download, with optional in-app purchases, and does GPS lap and sector times plus live tracking and leaderboards. It's on both the App Store and Google Play.

Here's the catch with every phone timer: the GPS inside a phone manages about one fix a second. At 90 km/h that leaves about 25 metres of track between readings, so the lap time is fine but corner-by-corner detail is thin. RaceChrono and Harry's both take an external GPS receiver to fix that. If you want the phone route against camera analysis in detail, we've written up Race Ninja vs RaceChrono, Race Ninja vs Harry's LapTimer and a three-way RaceChrono vs Harry's LapTimer comparison. The sample-rate maths is in kart telemetry.

Which karting app reads MyChron or Alfano data?

Own a kart with a dash? Then you've already got a logger, and these apps read what it recorded. They're aimed at club racers, and most of them now offer some kind of AI coaching on top of the traces.

Kart Track pairs with a MyChron 5S or 6, or an Alfano 6 or 7, and pulls the session off wirelessly. No cables, no exports. Its Speed Lab coaching reports come with a subscription (Pro gets 6 analyses and 3 coaching credits a month, Ultimate gets 30 and 15), and it runs on phones and in a web browser. The app itself is free to download.

Tenth Finder works with MyChron 5, 5S and 6 sessions and shows where you're losing time, corner by corner, on a track map. New users get 3 free analyses, then you buy credits in the app.

IRA (Intelligent Racing Analytics) reads the widest range of files we found: AiM, Alfano and UniPro dash files, plus RaceChrono, RaceBox, Porsche Track Precision and MoTeC exports. It runs on the web, iOS, Android, macOS and Windows. The Basic plan is free with 5 session imports a month, and Racer is €12.99 a month for unlimited imports.

Rotax TRAX is free on iOS and Android, but it's built around Rotax's own TRAX device, which you buy separately through a Rotax dealer. It gives you a driver score and coaching from that device's data.

If you've got a MyChron or an Alfano and you also film, you don't have to pick sides. Our MyChron alternative and Alfano alternative pages explain how camera analysis sits alongside the dash instead of replacing it, and karting data covers what a logger file, a timing sheet and camera GPS each give you.

Is there a karting app that analyses your onboard video?

This is our row, so we'll be straight about what it is and what it isn't.

Race Ninja isn't a phone app you download from a store. It's Racing Intelligence from the footage you already shoot: you upload GoPro or DJI video, the analysis runs in the cloud and you review it in your browser. You get lap times, sector splits, your racing line and AI coaching, all tied to the film, so you can watch the corner the numbers are talking about. You can see a finished one on the public showcase, for example a 17-lap DMAX session at Daytona Milton Keynes, and how to go faster in karting uses sessions like that to prove each tip.

The camera does the measuring. A GoPro Hero 9, 10, 11 or 13 logs its position about ten times a second, so at 90 km/h there's roughly 2.5 metres between fixes, against about 25 metres from a phone's own GPS. DJI Action 4, 5 and 6 and the Osmo 360 do it with the DJI GPS Remote. The supported cameras list has the detail.

Getting the footage up is where the companion apps come in. The Windows uploader is available now, with faster, resumable uploads so you can run an analysis between sessions. The iPhone app is in open beta through Apple's TestFlight. You'll find both on the Race Ninja uploader download page, and the upload help article walks through a first session.

If you want the coaching side specifically, that's on our AI karting coach page, and kart racing analysis shows the full set of results.

Which karting app should you get?

Drive hire karts at TeamSport? Get the TeamSport app for booking and times, and if you want to know where the time went, film your session and analyse the video.

Got no logger and want a lap timer today, for nothing? RaceChrono's free Android version or LapTrophy will do it.

Own a kart with a MyChron or Alfano? A logger app reads the file you've already got, and video analysis shows you the corner it's talking about.

And plenty of karters run two of these at once. They really don't compete as much as the app stores make it look.
