Hi Harry,

I've never quite gotten the data overlay and video to work quite right since I bought the app last summer- You may recall some of my posts then. Well, I went to another track event last weekend and experienced the delayed data overlay problem again. I'm not sure if the data rate is part...

Hey gents,

I purchased this app for autocross. I am only using my phone currently with no external devices. I went out to a few parking lots today to try to test the app. I only tried the “new track” feature as I would pick a point and then drive a few loops around the parking lot. I made certain...

I just used HLT for the first time at a recent track day. I was having trouble getting it to record my first two sessions. For my first session, it recorded for 30 seconds and then stopped timing. The second session I also was having trouble...

I'm using HLT Petrolhead v21.2 on a Samsung S7 with Android 8.0.0. Since my internal S7 memory is rather small, I entered an external memory card in my S7.

I have set HLT in the expert settings to record videos in a certain folder on the external memory card. However, when trying to view the...

I have an issue whereby HLT is not displaying the overlay data when I import/link a video.

I initially tried to link a single video for the 30 minute session but when I tried to do this it gave me an error about not being able to find the mast video file and/or it being corrupt. On a 2014 post ( )...

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...

I've been using HLT with just the Kiwi3 OBD2 adapter for a while now and its been working great. I decided to add an XGPS160 to the mix to get better accuracy with timing and GPS speed and location and stuff.

But when I overlayed and exported the video (its also the same when I watch the video...

Hi!

When using Harry's Lap Time Petrolhead version 21.2 on a Pixel 2 with an external GPS (XGPS-160), the accelerometer data is faulty and looks like the screenshot below.

When I don't use the XGPS-160 with my Pixel 2, the accelerometer data looks fine.

I use an iPhone. In the past, when I exported a video it was created in the m4v format. I just exported a video last night and it was created in the mov format. Why and does it matter?

Hi all,

I recently got an Apple Watch S3, and am not able to start HLT on it.

I get a screen message to "Please start Harry's LapTimer on you iPhone" and can't get past that.
I have tried starting the phone app first and also starting the watch app first.
I have also tried unloading /...

I have an older phone I would like to use instead of my newer phone in the event I crash a break the phone. How do I move the app to the older phone that no longer has cellualar service? The phone can still connect to the WiFi.

Hi Harry,

As you have biggest experience in this. Could you please provide your opinion:

For Harrys Laptimer - what is better Android or IOS.

So far I'm using IOS but have to change phone and thinking on Android :)

I think at least is easier to relink videos or add videos on Android device -...

Samsung s7. has worked great for almost a year. but recently I only get a few acceleration points per autocross run or lap. The live screen shows the acceleration values changing but the lap analysis and trak maps only have a few peaks. have uninstalled and re-installed app.

Hi there
I just recorded some data and some videos with my gopro.

After I moved the videos on my phone (LG G4) I tried to sync them with the data.
I had no problems with unedited files of my GoPro Hero 5 Session, works fine.

A few other laps, the video was too short to fit the data. So I added a...

I am trying to export a single lap. I successfully synchro the lap inside HLT and can watch the lap in HLT and it looks great.

But when I go to export it onto my phone, it only grabs 17 seconds. During processing it makes it to 22% and then stops. It won’t process 100%. Bug?

Lost my phone a month ago, had GrandPrix on it. Looking at my laptop Google Play shows that GrandPrix purchase correctly. But on my new phone (Samsung S9) the only purchase it shows is Petrolhead. Since I have a track day on Monday I will purchase the upgrade on the phone so I can link my GoPro for...

I just attended my first DE this past weekend and attempted to use the lap timer to capture the event. Unfortunately, I had moderate to poor success. I did manage to get one complete session recorded, but the on screen overlay (GPS, Accelerometer info) was off sync from the video by...

I have a sim card, which is 128GB, while my phone only has 10GB left. How do i go about defaulting saving the data and video to the SIM card?
