Harry's LapTimer Grand Prix App Reviews

You get more with this App than what you pay for. The only thing missing is a Desktop application to sync it to so overlaying videos is much much easier. Hopefully that could happen one day. But for now I love being able to see lap times and the data that goes along with it.

Extremely complicated and freezing all the time, but the developers really good and he responds to everybody on his Facebook page it means he cares about costumers!!!

Works great and reliable Could use some interface design update to look less like it was "built in the garage by a dude"😉 overall great value 👍 Makes track days feel like MotoGP Update - still awesome. Updates and improvements keep rolling.

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!

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.

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

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.
