I've been using HLT for a couple of years now on Android with a Qstarz 818XT gps running at 5 & 10 hz. The last 2 times (December and this weekend) I notice the following issue:

If I run HLT with no external GPS, I get gforces recorded and displayed in the video feedback and on the map

If I...

I'm running HLT on iPhone 7, Kiwi3 OBD, Hero 5. When I start a session, all is good. Strong WiFI connection, green and blue dots blinking on Camera icon in Timer view, etc. HLT records about 10 minutes of video data (4 or 5 laps), then I assume the WiFi connection drops while I am still driving....

I have Petrolhead with an iPhone 8. Since upgrading to the iPhone 8, my data overlays have been out of sync with the video. Any ideas or things I should troubleshoot? I think it is due to the new phone but I’m not positive. I never had this issue before the new phone.

Thanks

Hi All/Harry,

Have a track day coming up and trying to get the app sorted with my e60 (07) BMW 550i. I purchased the app for iphone as well as the kiwi 3 obd dongle. A couple issues I'm having.
1. There is no Throttle information coming through (as well as temperature, hp etc) however the rpms do...

How do I get the Guide Screen to appear? Whenever I restart HLT, it opens to the Home Screen.

First time user with Petrol Head Edition, see the video on my phone and then did the overlay. After overlay is complete get message that overlaid video can be accessed from Lap Details and and using the Photo App but am not having any luck finding either of these in the app?

Also where can I find...

I am trying to get the following setup running and I am having some issues with the multi camera:

Phone: Nexus 5X running Android 8.1.0
GPS: VBox Sport
OBD: OBDLink MX WiFi
Camera: 2 x Sony FDR-X3000
Software: Harry's LapTimer GrandPrix edition

The issue I am having is that LapTimer does not find...

Good morning. I have been using Harry's on my phone for years. I recently set the race car up to accommodate my Wife's ipad mini. Apple support has been telling me that I have to purchase the app a second time to have it on both devices. In the app store, it says that Harry's supports family...

Hi,

By mistake, my phone (Samsung galaxy s7 edge) was left in portrait mode lock, and app was recording video all the time in wrong orientation.
Am I able to rotate video and overlay it again?

Sub question: Because start/end on that track is not set correctly, can I change that and recalculate...

I was able to get this working, but since I got in my car and paired with my obdlink, I cant get any video from my gopro.

Harrys wont detect the go pro anymore.

anyone have any suggestions?

Hi, i recently purchased HLT and tried using it on a track day i have just done.
Half way through the day i had a pop up saying that my phone had run out of space but i thought that's fine ill just delete some old videos or something. But then the app crashed and when i reopened it all my lap...

Harry,

I haven't been able to see heart rate data in Grand Prix 20.2.4 on an iPhone 6 iOS 10.2.1 and I am trying to figure out why.

After searching the forums, I see HLT supports Healthkit devices. I believe my Polar H7 heart sensor is compatible as Polar supplies iPhone apps and the heart rate...

I have Lap Timer on an iPhone. I use it for autocross only, no track racing. LT works OK when it works, but my complaint is that it still pretends to be working when in fact it isn't doing anything. Take yesterday for example. I was at an event at a location where I have competed before, and gotten...

Very disappointed here. I've got lap data and video recorded *by* HLT. The video file is nice and smooth, but the exported video with overlay data has an unacceptably low frame rate. Why would HLT alter the video's frame rate?

(Lap, & video recorded and exported using an LG V10 and the HLT...

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 can't seem to figure out how to get HLT to connect to my Hero4 Session.

I thought it was recording yesterday at an HPDE but I got nothing. Upon looking closer, when I'm on the Timer screen and touch video, and select external camera only, it says in red "no external cam connected...

Hi Harry,

in last two versions of HLT i have huge problems with rendering on tab of Engine or Speedo. In most cases there are missing needles, sometimes dials. Im using mostly Engine page, because my car doenst have a Coolant temperature gauge and in winter its really helpful

I have last version...

I was encoding video from a session last weekend, and I was able to get it to do the overlay properly, but I had some sync point issues. While mucking around with that, I decided to upgrade to the GP edition (for the additional overlay data). Since then, I cannot use hardware acceleration,...

Exporting a complete session - about 18 mins. When Overlaying Video the app gets to 100% (32575 frames) and the app locks up. Have to kill app and restart. Sometimes it locks up at lower percentage completed - but I can usually restart and it completes. This particular session I am zero for 3....

So, no way to recover after an uninstall? I tried to downgrade back to Petrolhead from GP, and didn't see the warning buried in the database settings that all data would be removed.

This might be a crazy idea, but maybe have an option that backs up the database automatically on exit (or at least...

Hi Harry,

Recently my app V.21.2 on Samsung S8 does not show anymore the list of track times of other users for a specific track.

I remember not too long ago i was able to see other people track times - something has changed?

Thanks

When I look at the track map, no G forces are shown. This affected all the laps in the session (the other three sessions I recorded that day are fine and no settings were changed between sessions). The charts for these laps show Lateral Acceleration data, so I'm confused why the map doesn't show...

Using Android 7.0 on LG G5. When exporting multiple laps, or a single lap, if I turn off my screen, or switch to another screen, example - check a text message, it disrupts export completely. I have to restart export. Is this a bug?

Thanks,
Doug
