Pros and cons of Formulus Free app for iPhone and iPad

Formulus Free app good for

Missing some of the more complex formulas and proofs, but extremely useful when working in class or on a project and need to quickly look up a derivative, integral, or trig identity.
A good app for those who wish to refresh thier precalculus an calculus memories.
Amazing app! Perfect for vectors. Please keep editing to include more specific examples!
Simply put one of the most useful and best productive apps ever !!!
For people who just want a good definition this is the app to get. There are a few minor errors which I imagine are just typos in the DE section but great definitions of just about everything. Needs to be tweaked since it tends to freeze frequently. But still a great app
A great app to open up instead of running through your notes for basic formulas and definitions

Some bad moments

Has the formulas Im looking for, but constantly freezes. Plz fix this!
Starts but does not make its work on 7.1.2 Impossible to write to the developer
Right when I needed a reminder of arcsin derivatives before a test, come to find this app had none. Very disappointed.
