Fair to middling!

Ok, so I gave it an extra star over the three it deserves for being such a great idea. For physics and maths equations, this app is great. The chemistry section does look rather poor by comparison.

The app could use some cleaning up -- maybe some pictures in maths illustrating the geometries and vectors of certain topics -- and a more professionally consistent symbology. There are a few errors, and even some formulae that change symbols within the same page!

Besides a few errors, though, this is a great use of 99¢ for anyone who needs to look up formulae (like studying for the physics subject GRE)!
