Excellent

This is a very well organized, and very powerful graphing calculator ap. Unless you use a calculator all day, or need one on an exam, theres actually no point buying one if you have this $3 ap. The best Ive found. Nice layout, database of constants, matrix solver, the ability to plot multiple graphs simultaneously in different colours. Really great.
