Awesome app! Used this for the first time at Lime Rock Park in CT on 18-Sep-2018. Super easy to use - just press the big Start button, it prompts you for the track and then it selected Lime Rock by itself since I was there. And that's it. After each track session you stop it, and review the results. Lap times, min/avg/max mph, etc. Confirmed the times against GoPro video and it's spot on. Love it!

Purchased the pro version in the app and used this on Chang international circuit in Thailand. Never have a single problem. The app is very easy to use, navigate and has very easy to understand UI and functions. Connect with obdII and use gopro11 to record then sync the footage with metadata was easy as pie. The footage can be exported in laps, sessions, timeframe with a very easy to use navigation timeline. Will recommend this to everyone I know!

Very good app and easy to work with. I always wanted something like this for my track days. First i used the free version . Enough to keep records of your laps and let you focus on driving. Now i bought some GoPro with GPS and i've tried the pro version in trial mode. Next level completed successfully. I will definitely buy it in the near future.
