I use Harry's with a Kiwi bluetooth OBD and a Dual GPS
I find it works well and very accurate, typically within .05 seconds off of the transponder times
The dual GPS is 5 hz and the builtin GPS in an iPhone is 10 hz so around 15ft IIRC for the 5 hz

I've heard good things about those brands and the iPhone, I have an Amazon Android BLU R1-HD (with "special offers"), it is a pretty low powered phone - when I just use HLT with a QStarz 818XT GPS at 5hz it is great. I think adding in the OBDLink is just too much for my phone and it slows it down...
I don't care as much about seeing RPM, but I would like to be able to see the throttle position in my videos to help identify spots where I am not getting on the gas when I could/should be....
Here is another session from Sunday, this one is from Sunday morning, it has some more Boxster time in it - we gridded up and ran a few laps with me in front, then he caught me and I tried to keep up.
If you have never done that before it is a lot of fun
Making these videos is very educational - I have now learned that I rub my face way too much when driving, and also when I give a point by I hang my elbow out the window after the point by, and then pull it back it when I get back on it. I am surprised I have never been black flagged.. Maybe my elbow is just propped on the side rest. Either way though, now that I know I do it, I can try to stop...

How do you embed the YouTube video? I tried several ways, but didn't succeed.
