Track timing differences

[Nathannnnn]

Hey guys got a question for those of you that use Racechrono.
How accurate do you find it compared to Natsoft?
I'm using track addict (because iPhone) and find it's about a second faster than Natsoft timing (Winton)

I use track addict (also because iPhone) and mines always been within .1-.2 of natsoft. I actually find that it's usually slower than natsoft.
I think I'm going to give Harry's a try

I wish racechrono was available on iPhone

I've heard good things about Harry's. Might have to give it a go!

Racechrono with Qstarz 10hz was within 0.01sec of the natsoft official time for me. That's pretty impressive.

Without the external GPS it is not accurate at all.
