Harry's LapTimer Grand Prix

Harry's is an excellent choice to augment your track time. The replays, the stats, the overlays, they just enable me as a novice track goer to look back and identify what I need to focus on for constant improvement. Harry's holds ton so stats, and also offers the advanced functionality to add external devices (better GPS, Go Pro Cameras, etc) and to slowly upgrade my monitoring equipment slowly as my skills dictate.

I just upgraded and the app crashes all the time. For some reason the track list is empty. So I'm at the track today and I can't even use the app. Of course there is no indication in the app on how to get help. Stay away

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.

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.

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.

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.

Never works, out of 10 track days this thing worked twice. Waste of Money very complicated

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.

The app not working Is stock My I have iPhone version ios 13.3 Please refund my money Thanks dear

Been using the App for several years and it packs a ton of capability into your hands. It does require some trial and error and dedication to learn how to use properly, so that will deter some, but for those that want data and video overlay in a tight little package this is the best I’ve found. Harry’s support and updates are top notch!
