Really Great It has a Great amount of tools. I really like the "tests" you can run on the phone's display. When I read the comments in here it seems like that people don't understand that it's used to calculate wether or not other devices displays are HD, which you can do with the different calculators in the app. Really great app.
Nice i like it.
HD or not
Not for me Is it me or this app just gave me crap?.. Knowing stats is nice but not like this!!! it's like knowing your height but you can't do anything to be taller LOL! Hate nerds apps! hate it!!!!
