Extremely helpful to improve your lap time
Uli-OMA
The information that this app delivers has been incredibly helpful to find a better line at the race track. Comparing the data collected from your personal fast lap to the fast lap of others shows you where and how to improve. Highly recommended. Thank you to those who are sharing their lap data.

Love this app! Works great for racing. If only I could figure out how after setting the direction to submit it and go back. I get stuck on that page and have no way out. If I could do that then I could certify some tracks.
Great Product - Please read if using on GTR

This is a great product. Just by itself it is easily the best thing and easiest to use for improving laptimes. Great customer service as well when I was at the track and needed help. GTR Owners - I spoke with Harry, the GTR ecu is a bit wonky in how it works. So the OBD2 functions won't read proper values. He expects this to be fixed by version 19.1 which is expected no earlier than middle of this year. Just an FYI because I couldn't find anything on the forums about it.
Best telematics app for trackday enthusiast

Have been using this app since the old days on the Palm Pilot. Harry's dedication to continued improvement based on feedback from the user community and his own experience as a fellow enthusiast is unparalleled. Highly recommend the full "Grand Prix" version.
Great Lap Timer

As a habitual DE driver I use Harry's Lap Timer and find it excellent. Is it pinpoint accurate (using the iPhone's internal 1 Hz GPS)? No. But it is more than accurate enough to use for gauging progress, examining split times, recording video of your line, etc. Unless you're going to commit to serious data analysis of your lapping, Harry's is all you need. Great app!
So much potential so many problems

Been using this app for 3 years so all of my complaints are of repeated use over this time. The crashing is just so frustrating, since I Autocross, tracks are not available and it seems the simple task of setting a start and a finish point results in an app crash every few times which requires re-walking to the start line and hoping it doesn't do it again (and yes it sometimes does and no if it crashes the poi do not get saved). Would help "A LOT" if you could set start and finish independently with the wizard.... GoPro video linking and downloads work properly about 5% of the time, it usually downloads the movie as an unlinked copy which is fine but the manual linking process is either out of sync or causes another app crash. Scrolling through graphs or opening graphs causes crashes constantly. The sync process for videos is really not intuitive at all, it's easier to just try and repeat overlay'd videos over and over until the PnP video is aligned. It needs to have a preview (maybe just 5 seconds of video), or split screen video, waiting 5minutes to render an entire file is silly. Deleting video should UNLINK it from a lap and not delete it off the device. Or have some undo, I've accidentally deleted the wrong video a few times which is what really really really pisses me off and what broke the camels back. At this point I'm done with the frustration and will use something else from now on, and yes there are other options out there.
Misleading features

Not worth purchasing (at the moment). The app is misleading if you have the latest iOS. The app will not support the multi-cam as stated in the description.
Need better autox setup interface

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 I'm sure. I don't know what "purge" means. Why not use words like "reset"? I would like to be able to set the start line and then, while I'm 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 it'll be 5 stars! :)
