Harry's LapTimer GrandPrix

Latest version does not work in ios12. Tried with 4 different iPhones.

- Only one configuration available for Moscow Raceway. Please add more configurations! - Often fails measurements. Overall no more than 30% of successful attempts - very weak performance. - No progress in 2 years. Conclusion: Waist of money for such poor performance. Please give my money back!

I am using this app for a couple of years but main problem still exist. Freezing of menu when you want to overlay video will be impossible to complete your work. I use it with GoPro camera and VBox sport, compatibility is perfect. But impossible in 99% to overlay video without problems. Also lap timer maintain big load and on iphone 6 plus cpu, as a solution i prefer to put air conditioning ventilation directly on iphone. Harry! Thanks for app! But there is a long way to go..

+ Работает с OBD II адаптерами + Запись видео с наложением данных + Высокая точность при использовании внешнего GPS + Мониторинг во время езды и анализ после - Глючит под iOS 8.0.2, ждем обновлений.

after installing new ver. all data is erased 😡

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
