I created my own data logger hardware including GPS and ECU data feeds, I linked my Go Pro Hero 8 and got video feeds. The app is quite customizable and initially you are going to work through the best setup and learning how to do the video side of things. Once you are past that learning phase it gets a lot easier and its a turn on, connect your camera and go which is great. I'm more technical and part of the fun for me was making my own hardware and configuring it - that side of things is not for everyone - I loved it.

Using internal camera, Pressed record for video and it says it is , time counts down but nothing is recorded, gutted, was really looking forward to watching my laps back from the day but I have nothing. Without the video I might as well have the free version than waste 17.99 on this. Real shame. If know one helps me then I will probably ask for my money back

Highly recommend this app. Amazing way to record data for post processing as well as compare data between sessions while at an event. It also has extra features to record/export video, but I typically just export a CSV that can be fed into RaceRender.

Great app for motorsport, I use it for club events of various kinds, and even for stuff like snowboarding. Works really well with a Garmin GLO Bluetooth GPS. Great support on the forum, and easy to overlay video and export to YouTube, and to analyse different laps to find out where you can improve lap time

Most unintuitive app that never works for me. Hope you feel like messing with settings every single time. Sessions don't record properly, randomly starts and stops. Gopro sync for videos is a nightmare. Get a real setup and don't bother with this amateur trash.

I use the app in my circuit race car with an external GPS and it works brilliantly, I do not have a Go Pro camera but have one of these generic ones, video overlay is a breeze after the race day, support for the use of the app is amazing.

Very difficult to use. Poor video quality. Used to be adequate back in the days when there were no alternatives. I think the Devs should start over.

Does not work on Surface Duo :*( I got a message saying the video was imported successfully, but then there was nothing there. No video showed up.

This app is awesome! No bugs, clear instructions and faq. If you need help their customer support is fast as well. Wish I could give more than 5 stars!

Excellent overall. if I were to improve i would like max lean angle gauge added in addition to the current Dynamic lean angle. Great Job

The best racing app there. Simply connect it to a bluetooth for better accuracy.
