Hands down winner

This is my firs time reviewing an app, that’s how extremely satisfied I am with RC Pro. I’ve tried Harry’s Lap Timer and Track Addict. RC Pro has the best and most simplest and reliable functionality but my favorite feature is the analysis tools. Harry’s and Track Addict can’t hold a candle to RC Pro! There’s lots of data available, it’s simple to interpret and consume and an invaluable post race tool that has undoubtedly left me a better racer and faster driver.

Very good

I use racechrono pro with gopro 7, racebox mini, and veepeak obd2 for autocross and track. It works very well.

Doesn’t work! Waste of $19!

I ran this app at both Road Atlanta and Daytona. Neither time was the gps accurate enough to even remotely function properly. You have to buy a better gps for $100+ for it to work. It should be noted in the description that my phone’s gps (iPhone 8) isn’t accurate enough.

Update:
In response to the developer’s note below, my phone was mounted to the front windshield not in my pocket. I have a 100% stock Camaro SS 1LE, it certainly isn’t a racecar.

Again you need to note on the app that it requires an external GPS!

Developer Response ,

Hi, sorry for the bad experience. The iPhone 8 is quite OK for casual track days, but you cannot have the phone in your pocket. A phone holder is needed to keep it in view of the sky (and the satellites). If you have a racing car with high corner speeds, or need to keep the phone in your pocket, only then external GPS is absolutely required. You may also want to get an external GPS to improve data quality for better analysis.

Update: Yes, maybe the expectations could be managed better, but let me assure you that the app works even with the internal GPS on iPhone 8. This has been tested repeatedly. Naturally it will work better with the external GPS. It may be, that in your case there was something else that affected the data quality, such as device malfunction. Also it could be your expectation of the quality of the collected data was just too high. If you'd like to continue the discussion, you're welcome to contact RaceChrono support, and we could take a look at the recorded sessions together.
