User reviews

Jetzt auch mit CarPlay

Mega App jetzt nun endlich auch für CarPlay freigeschaltet. Super Support wenn man eine Funktion mal nicht findet. Auch die 10tel Sekunde genau verglichen mit dem offiziellen RCN Timing.

Schrott

Spart euch das Geld. Schlimmste App die ich jemals gesehen habe.

Finicky, legacy, doesn’t work well

This app is not easy to use and even if you learn how to use it, it doesn’t function properly most of the time. I did 50 laps at Laguna Seca last weekend with my phone connected to my GoPro and my OBDLinkMX+ and neither the GoPro footage nor the OBD data was recorded for even a single lap.

At the beginning of each session I carefully made sure everything was configured correctly, thinking “maybe it will work this time”, but no. This app does not work well at all.

It is a legacy app that hasn’t been updated very well over time and is lacking in reliability/ease of use. I do not recommend wasting nearly $30 on it. If you are just looking to time your laps, the super basic version might be okay to use.

Personally I wish I had listened to the reviews before wasting my money on this app. Do not make the same mistake I did.

Rubbish

Couldn’t even get this started, should be just start/stop review data… but awful layout and requires add on’s for everything, basically they just want you to buy the full version. Don’t bother!

Absolute garbage

I downloaded this app last year for a DE weekend. At the time, I found it very user in friendly and annoying, but at least it saved my videos and times. Yesterday I used it again for the second time: it froze in the middle of data transfer to my phone, crashed, and then proceeded to delete an entire day worth of lap videos. And then it did it to me again today. RIP video of COTA PR time. Harold and his developers should be ashamed to be selling this app. It is absolute rubbish.
