Harry's LapTimer Grand Prix App Reviews

Is iPhone6 supported? The app keeps freezing while navigating in the menu... This is barely useable as it is. Please help

I just upgraded and the app crashes all the time. For some reason the track list is empty. So Im at the track today and I cant even use the app. Of course there is no indication in the app on how to get help. Stay away

Harrys 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. Harrys 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 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..

App keeps quitting when I rename an autox track and create the start and finish. I should be able to set the finish line first if I choose. I have reset the s/f line by accident because I clicked "Autocross". There should be a pop up asking if Im sure. I dont know what "purge" means. Why not use words like "reset"? I would like to be able to set the start line and then, while Im walking the course, close the app or shut off the screen...then go back in the app and set the finish line. Add these and itll be 5 stars! :)

Bought this app with high expectations. The user interface for uploading and overlaying videos is incredibly difficult to use. Trying to get GoPro video as master video is almost impossible. Its not worth the effort. Im a youtubers and make videos and vlogs so I know it shouldnt be this difficult. I finally got an overlay on a GoPro video but it required using a computer and then syncing the video its still not perfect and the video is not separated per lap so I have to do that individually also. Waste of $28 for me.

This is my favorite app on my phone. Fires up and works as expected every time. Video is great and love the overlay.

In preparation for my next track day Ive purchased this app and have been trying it out around town. I think Ive finally figured out the basics through trial and lots of error. MultiCam worked once, never again...cant figure out how to overlay external video from GoPro. Documentation online looks nothing like this version. Screens are impossible to navigate and make no sense, red flags everywhere with no clear direction on the problem or resolution. Time to take the core of what works well and start over with a new intuitive and simplified interface.

I was searching for a user friendly, cost effective way to track my progress and it share it with the world, as I have just began riding my motorcycle at track days in Texas! The fact that LapTimer has so many tracks Pre loaded into its system for easy access makes this app a no brainer! Multi cam recording and then adding the track overlays are so awesome! I will be using Harrys LapTimer and the last track day of the season at COTA (Austin,TX). I cant wait to show off the footage. I have recommended this app to lots of my friends looking for a way to get lap times with out braking their bank accounts! Its easy to use and there is a lot of documentation available if you can figure something out. Plus the forum! Nothing compares to Harrys LapTimer!

I have used Harrys LapTimer many times on the track and it is awesome! It not only creates awesome videos to share with friends, but it is also a great tool to utilize that will make you a better driver. It definitely adds to my track day experience and I highly recommend it!

I downloaded this app to run a few laps in Interlagos, famous F1 circuit. The other drivers were all anxious to see this app capabilities, too bad it does not open, it crashes before initiating. Cant tell if it is good or bad since for now it is not working. I have reported the problem on their developer site, lets see if they can solve the problem.

This is the best way to view and analyze lapping data. This app gives you some extra information (over and above the iphone app) while using the same views as are included with the iphone app. The new diagram view lets you see your current laps speed at any point on the track as well as that of your reference lap (simultaneously). Very slick! Also gives you the accumulated time differential at any point during each lap for the two laps selected. And now with the new user-configurable color selection relating to lateral Gs on the lap diagram, I can better analyze which corners I need to work on. And the elevation map is particularly interesting, particularly at a track like Road America which has 170+ feet of elevation change. Have used at three tracks so far this summer with great reuslts. Go Harry, go! Version 14.2 update: Same quality as before, it just works, and continues to amaze my rack buddies with TraqMates. Absolutely no issues, the software works amazingly well, and next time in Germany Ill search out Harry and buy him a beer!

I just took version 15 for a drive at Lime Rock and am extremely impressed. My installation uses the Dual XGPS150 @ 5 Hz, mounted to the harness bar vith the Makayama camera mount for the iPad. Easy to setup and use, excellent data capture and analysis tools...certainly an excellent value when compared to other dedicated systems. Excellent customer support via the authors website (and email) ...he clearly is a driving enthusiast and shares our passion. Off to Watkins Glen and Calabogie soon ... Yes, he has GPS data for those and many other tracks available in the vast track database.

Well I have yet to use on circuit, that will occur on May 20th. Have tried using the trip A-B mode from home to work, only owned for a couple days, but the program has crashed and when it does the data is lost completely. I noticed this on Lap Timer Pro on my iPhone as well. Just worried while out on track if the thing crashes that data is lost making this a bit worthless. So can only give it 3 stars at the moment. The potential is definitely there for a full 5. Have ordered an external GPS receiver and OBD2 link suggested by Harrys site. Wont have them in time for the event, but next time for sure.

Ive been driving on track for the last 5 years. The tools provided by Harrys Lap timer are very helpful. Ive gained real insight into where on track I am loosing time and what I need to do to address. Im using the suite of tools. Timer on my 3GS iPhone, an external GPS as well as the OBD II interface to collect the data. Im then using the iPad for review and analysis. The next step up in data acquisition and analysis in my book would require an additional investment of >1K to get more meaningful data. Great product Harry!

Great app. Easy to use with great video

There is nothing else quite as awesome as this app. GPS+video+OBD-II data+custom tracks=amazing road or track videos and detailed data for number geeks. But the interface is arcane, confusing and not entirely consistent with iPhone conventions, so it has a steep learning curve. Plan to spend some time figuring it out. But once you do, youll be tracking your track days, autocross, and perhaps even your daily commute, and making video of your best laps with data overlays and picture-in-picture of your reference laps or 2nd camera. Fun stuff, worth the work!

Harrys lap timer is great, I use it at all of the HPDEs I attend. The graphs generated are great tools to learn where you can pick up a few seconds. The videos are excellent and allow you to show others just what youre up to on the weekends!

This application is just plain amazing. Used it at Watkins Glen and it performed great. Even synced some gopro videos. The videos look so professional and give you something to share with others. Highly recommended.

Works with multiple cams
