Not that I’ve been lucky enough to use it on the track yet but...
I’ve had fun experimenting with TrackAddict, it works real well and you can use their other app I believe RaceRender to overlay external action cam video onto the data. If not, you can just use TrackAddict to record video and data with your phone no problem. Both are free, for Android and iPhone.
TrackAddict can be used for established race tracks, autoX, drag strips, rally, etc. Pretty cool
Those phone apps are pretty cool. I used to use harrys laptimer which allowed you to overlay data onto your video. You should get a stand alone gps module though, your phone gps is only accurate to about 15 feet. A gps lap timer or stand alone gps module will get you within 3 inches which is what you need to use it to improve your driving.
I downloaded RaceChrono to my phone. Free version, so data was somewhat limited. It appeals to my apparent need to have spreadsheets in my life to study, so I‘ll probably upgrade to something that correlates ECU data with lap timer data.
I do wish I had a better laptimer. I have the original AIM Solo which is gps only. They have better ones that show your brake force, throttle input, RPM etc. Eventually I'll upgrade but what I have now is fine.
Man what a world we now live in. No such thing as GPS & a lap time was my wife sitting on the pit wall with a stop watch.
I had a Jansport 4 person tent that was easy to set up. It had external fiberglass poles. I never used it at the track, just on family camping trips. At the track I'd always stay in a nearby fleabag motel. Unless it was Mid-Ohio, I'd be home in 50 minutes. At Nelson I'd stay at dad's place.
My buddies & I would split up the gear so our load was less.
Have fun at Gingerman.
What a time to be alive. I love technology and how it can improve driving. When I first got into going to the track 5 years ago or so I had an excellent instructor that put data in my car (once I reached intermediate level) and he had me take different lines on the same corners then we'd go look at the data and I'd make notes on a track map what line I should be taking. By the end of the day I went from a 3:02 at Autobahn CC (full course) to a 2:47 by doing that.
I've stayed in some fleabag motels on occasion when venturing out for track days. My girlfriend and I called em toot motels though
And thanks I'm looking forward to Gingerman, haven't been there in 2 years. It's a fast track but I think it gets a little boring. It's pretty flat, after driving tracks with elevation changes, flat tracks just don't do it. I'm a sucker for blind corners too, dunno why I just think they're so much fun. Grattan is full of elevation changes and blind corners.
