As already said they are very accurate when compared to a timeslip on the track. We use them on the street alot. So far 5.30's on the crap road we have here but keep working on it.
it never seems to fail, or amaze me............... all the features available to a "smarter than me" phone, it almost makes me want to get one...............
Here's a track timeslip vs Dragy comparison from one of my stick shift Hitmaster customers...

I just used my Dragy for the first time last night at the track.Very accurate when compared to my time slips. Questions for you: is there a way to get my graph onto a screen larger than my phone? In the app, i cannot see an export data option or anything like that. I'm wanting to have a better look at my acceleration graph and try to determine where my shift points were. It's just hard for me to really look at it on the phone.
