iPhone Data Logger For Autocross
 

Does anyone have a recommendation for a good iPhone app to use as a data logger for autocross? I see a few out there that are mostly focused on track use. I'm looking for something autocross-specific, or at least with strong autocross capabilities. What are you guys using?

I tried Harry's a few times, I think my phone wasn't quite up to snuff, datarate wasn't high enough and final video output was super low framerate. Might be difficult to pull off something quality on a phone period, but maybe a recent iphone with Harry's has enough grunt to pull it off. This was ~2 years ago for me on an HTC One (M7, so a 2013 phone).

Camera on the roof, phone mounted inside via suction cup, Bluetooth OBD2 dongle paired to the phone for car data, used Harry's to mash the two together. I have no doubt you can get better results than this with a phone app, I just haven't put in the effort to do so.

You can see that I didn't perfectly match the data to the video, and the accel data is cocked a bit sideways, there's some untapped potential and probably many more things wrong but I decided to focus on other parts of my autocross instead.

If you want just raw data pushed to an excel file you could try messing around with the Torque app for free, at the very least it will give you an idea of how capable your phone is, mounting positions, data collection settings, etc.

Definitely interested to see what others have tried.
Solo Storm seems to be the big name, but the price tag is daunting.

:cheers:

I run SoloStorm with a Note 8, external GPS, and OBDII and it works great. (Had it sync'd with my hero 3, but have yet to bother with syncing my new go pro)

It's not iphone compatible, but after running it with a tablet, I prefer it to my phone anyway. (And android tablets can be had pretty cheap)

Using harrys as well but I dont do autocross, so yeah, there's that. I dont have it connected to external camera or bluetooth, so its basically the phone just recording data using GPS data, here's the result (phone was on the rear windshield with a ram suction cup mount):
