Ratings and reviews

Be prepared to pay for pro no matter what if you want your data. You can only export 120 seconds of data without pro which is not enough for most tracks. Otherwise they keep a stranglehold on your data until you pay them. If you want your times from a day you have no choice. They should give you a one time export at least for testing. If I cannot see and use all of my data at least once its hard to pay this extortion.

GPS device was found on the 3rd try - As soon as it connects to your RaceBox Mini S you will be told you have 5 minute trial and need to upgrade to record more. Since the RaceBox Mini S has terrible software that crashes all the time I was hoping to test this out and see if it worked better then the free software that came with the device since they have this software as a supported label on the RaceBox website I thought it would be more of partnership between the companies - I was wrong.

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!
