I love it.

Found the app on morning break, drove to the store on lunch to get $25 gift card, drove back, bought it, and showed it to the guys.
We spent afternoon break thinking about all the ways it will save us time and aggravation, as we work in a "get this done" kind of environment... no prints or engineers to fall back on... Ive had it for about 6 hours now and I cannot put it down. I will be helping the developers as much as I can, because this is simply an invaluable app for me.
