Helpful but terrible app for physics – iPhysics™ Pro Review

When I first opened the app I was told to by the Pro version for $2.99! I didn't want to but there is a lot of material that is not available unless you buy the 2nd version! Also the app doesn't offer any quizzes! Okay maybe one or two, but come on one or two! I mean total; completely summed up. Just a download a different physics app!! If you are only interested in positive reviews then the app does completely go over the necessary concepts of physics with formulas, examples, and links to Wikipedia! Just remember, $2.99!!! :(
