RaceChrono Pro

Update my review to 5 stars.

Sophisticated and easy to use. Being able to compare a large number of metrics, from any two laps from any session, on one graph or table, to retrospectively analyse your technique. Handles scaling the two laps on the one graph perfectly and seamlessly. Much technical capability which you may need, and no gimmicky 'features' which you don't need. Simple, minimal, easy, powerful. Love it.

After using the OG hardware version years ago I was really happy to find this in the App Store. I’m using it on a motorbike in my pocket so sometimes the laps join together because it can’t identify the start/finish line. But I just split them up after so it’s not a problem. Having a way to do this on the app would be the only thing I would change. Thanks!

It’s ok for a very rough idea on lap times. Extremely inconsistent and not accurate at all... I would look elsewhere before using this.

For what it costs, I get other fun features with TrackAddict . Racechrono is missing more gauge design options. The landscape mode is bothersome since you have to press that button to allow the rotation for the camera. Also the app has issues exporting to the camera roll.

This app is a really good alternative of expensive lap timers like AiM. Would be 5 star if it had a bit more overlay customizations and CarPlay support.

This is the only track data analysis tool I use and I don’t need any others. I use it with my Go Pro Hero 9 and it gives me just about everything I need. Video synced up with track map and speed graphs, sector and lap comparison with your best laps, top/min/avg speed, nice visual overlays My only gripes are that I wish it had the ability to control playback speed so I could watch comparisons closer, and video compression. Since this is only for iPhone/Tablet you’re more space limited and GoPro files are huge, so if I could in app compress them it would help a lot.

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

As an app developer myself, I understand how important is for independent developers to receive feedback on the app they poured their heart and soul to design, develop and maintain. So here’s a shout out for a job well done! I’ve been using your app for few years now for autocross only events. I average around 30 events per year, which probably puts me in the addicted category. I find the app an invaluable resource when I’m out at an event, as well as after the event. I use it to split the course in multiple sections, then analyze whether different approaches in a particular section work better than others. After the event with my friends and competitors we combine our data to see how each of us drove. One idea would be to come up with an online service that lets us share an event’s map, then have everyone signed up for that event upload their data there. This way we can look up in real time at other people’s data. I know this is a lot more work for you, but it could be a potential recurring revenue stream after you sold the app. One complaint I do have is that for the life of me I cannot figure out how to have the video camera start recording automatically when I’m at the start line, and turn off automatically few seconds (perhaps configurable in the settings) after I pass the finish line. The online FAQ is not very clear on how the video recording is supposed to work. At the moment I’m not using the video recording part of the app, which is really a shame since this would be extremely useful to have.

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