Garbage

1) Doesn’t work with GoPro
2) only uses the RaceBox GPS (no accelerometer
3) even when it says the RaceBox GPS is connected, it won’t use it

This is the first time I’ve ever wanted a refund for an app; wish me luck in obtaining it

super plus klasse :)

nutze die app sehr lange schon auf trackdays. Nun auch in stvo land zur verbrauchs und reichweiten ermittlung von batterie autos

Poor- avoid

Unreliable and inconsistent. Just sends a copy and paste message when you raise issues. Don’t waste your money.

Absolute junk app

This is the most money I’ve ever spent for an app to be such crap it doesn’t function anything like how it was described. I spent an entire track day trying to calibrate it and wasted more time than it’s worth. It told me I did a 45 min lap time around COTA for one of my sessions. Just junk. The developers should be ashamed at the steaming pile they’ve wasted their college degrees creating.

Very comprehensive but adding video…?

This app is great, comprehensive and analytical. I wanted to use it to insert telemetry into a video and it is NOT intuitive nor remotely easy as RaceChrono Pro and it was difficult! I probably won’t be using.

Kleine verbesserungsvorschlage

Leider wird die geladene Strecke nicht angezeigt und somit ist man unsicher ob die rixhtige Strecke geladen ist und wenn dann das Netz schlecht ist steht man dumm da

Verschiedentlich wird kein video aufgezeichnet obwohl es eingestellt wurde

Compatibilité Go Pro ?

Bonjour, j’ai acheté lap timer Grand prix ! Dans votre descriptif vous annoncez être comptatible avec les Go pro ! J’ai donc acheter la Hero 9 avant d’avoir acheter lap timer ! Votre app ne reconnais pas la hero 9 ! Avez vous une solution pour moi ? Pensez vous avoir une mise à jour prochaine pour rendre compatible votre app avec les nouvelles Go Pro ? Merci cordialement Mikael

Great app

You can’t really beat it for the price. Lots of data for that price. Know that it’s not as accurate until you purchase an external gps. Even with that, it’s still going to be cheaper than a dedicated gps lap timer. My current set up is an old iPhone, xgps160 and Harry’s .

Some folks mentioned it’s counterintuitive. If you can’t figure out how to use it, maybe riding on a race track isn’t for you.you push like 3 buttons to start logging laps. Maybe more if you haven’t loaded your track yet. So yeah, saying it’s counterintuitive isn’t a true statement imho.

Support is terrible

Harry’s Forum don’t work. Can’t login, can’t register, can’t contact an administrator! Therefore updated info is hard to get. Harry has not updated the app to use the most recent GOPro 9’s. It is impossible to know if a $400 purchase will work unless we try. No thanks Harry, keep it, we will move on to more responsive application developers.

Complete app for experts

I have been using this app for almost two years now. It takes some time to set it up and learn to use it but after that it does everything. Now it looks like the app hasn't been updated in a long time and the video import doesn't work well anymore. I tried to do the usual, but the app can't show the video properly and finally crashes. I have iOS 13.3.1. Apple might have changed something in iOS that makes the app not work well. Update to the app is definitely needed.

Not compatible with GoPro Hero 7

Very frustrating it doesn’t work with GoPro 7/iOS 13. Can’t overlay any data onto recorded lap video.

Das Beste

Ich habe mehrere LapTimer getestet. Definitiv der Beste. Sehr zu empfehlen.

Poor

Unfortunately this app has stopped being an effective tool.
On my last 2 outings oulton park and the ring both times it has failed to consistently acquire lap times at the ring no lap times at all. I have tryed mounting the iPhone directly on the dash. Still nothing.
Used to work now No good

Tried with both
iPhone 10&11 same results
