Want to show your drive to your friends? LapTimer Petrolhead and above generates beautiful in car video recordings with all kinds of data overlaid, ready to be presented - e.g. on youtube.

Complete app for experts
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.
The short version: This app is garbage, over complicated, counterintuitive, doesn’t work as advertised and constantly freezes/crashes. Don’t waste your time or money on it.
The long version: There is a 29 page pdf on their website that only deals with syncing up video. It is outdated, over complicated and should be simplified. It references apps to use for multiple cameras that are no longer available. After reading the exhaustive instructions because the app itself is not at all user friendly nor is it easy to figure out, I took some test drives with it and my GoPros. The app would either freeze up or crash, multiple times, resulting in me having to pull over and reset everything each time. When I finally recorded some decent video from all three cameras, I was unable to sync the videos together with data overlay. I came back later to try again and the app says that it can not locate the videos. This app is a huge waste of time and money. I would not recommend this to anyone.
Very comprehensive but adding video…?
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.
