Ratings and reviews

Great app. Would love the ability to create some "Math channels" to generate some more useful plots from combined channels, but overall the ability to quickly review data and get real time feedback on track has been great. I would love to know if the app will be getting support for any additional devices anytime soon. • Newer GoPro's (12, 13) • DJI, Insta360 action cams? • Racebox Micro

Videos from my Gopro will not load. I have attempted to contact support several times through their website, email, and the play store with no response. Since I have been unable to use the app at all, I requested a refund, which was promptly denied. I downloaded the free version of Racerender, which is working flawlessly.

An excellent platform for data acquisition that is widely compatible with tons of devices. The UI is in a league of its own with fantastic displays for data traces, track position, and camera, all time synchronized, allowing for review of the same lap from several angles. Excellent support and reliability.
