Hi, Half way through a track day on Monday, I went to open Harry's Lap Timer on my Samsung S6 and it tried (and failed) to resort the GPS. It now does this every time I try to open HLT and I've even tried turning the phone off and on! Haha I did a search and found a guide on how to resolve the issue...

Hi Harry, I'm now using the Samsung S8 and appear to have the same problem sound not being in sync. I've tried turning off the beeps but I still have the same issue. Is there anything else I can try? I'm going to the Nürburgring next week so hoping to get it fixed before then if possible!

Thanks Harry, I couldn't find any settings to throttle the GPS device to 5Hz, a quick search shows I should be able to do this using a Qstarz programme, possibly this one? http://www.qstarz.com/download.php?t=5&m=BT-Q818XT I'll give it a try tomorrow to see if that helps. Using the GPS at 1Hz, the r...

I've had another play around with it and I'm wondering if it may shed some more light on the problem... All of the previous tests with external GPS had been with it set to 10Hz so I've updated the list and added a few more...

Yes, I tried a few different combinations of new recordings and then played back the overlay...

Thanks Harry, I've been having a play with the OBD tweaks settings this morning and when only connected to the OBD reader, it was much smoother. However when it's also connected to the Qstarz GPS at the same time, the rpm becomes very jumpy again as if it's not being updated frequently enough and th...

Thanks Harry, that's great. I've uploaded a clip and I'm not sure if this is as much as I can expect from the OBDLink MX with my car or if I can do something to improve it? It seems a lot more jumpy than other footage I've seen... https://youtu.be/8Fhvi1jsxU4

Firstly, big thanks for helping sort out the issues I was having on track yesterday! I managed to get a good few recordings in the afternoon. One other thing I've noticed is that the latest update seems to have lost the option to use the GPS speed rather than OBD speed in the video overlay? Is there...

Hi, I've been using Harry's Lap Timer this year on track and I love it! It's a great app and I love the resulting videos using my Sony Z3 Compact. I was on track at Silverstone last weekend and noticed that the GPS didn't seem as reliable as normal - https://www.youtube.com/watch?v=wHyoiICFKjc I kno...
