RaceChrono Pro for Android

Import of .MP4 file fails but .mp4 works.. this is insane..

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.

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 (Android 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!

This app is awesome! Way better than others I've tried (Harry's, solostorm, track addict, etc) and it's priced right. I have it paired with my 20Hz VBOX Sport GPS (also highly recommend). I mainly use it for predictive timing and data analysis between sessions or post event (SCCA autocross and karting so far). The interface for setting up devices is intuitive and I've had no reliability issues after using this app for about 12 separate events. I like that u can set or change start/finish markers before or after running. The ability to toggle "Driving line color channel" is a cool feature as well. I usually set it to Time Delta. I gave only 4 stars because of one needed improvement. In session Data analysis, the line colors are confusing since the baseline lap color is the same as the lap you're analyzing. There either needs to be a larger difference between the colors, or a label/legend added at the bottom.
