Not enough preformed templates.
Because the app will not allow you to input values manually without using a preformed template. The types of polynomials that can be used as inputs is limited and greatly reduces the value of this appHelps with one specific calculus task
I wish I had this app when I took calculus class. Partial fractions wasn't that difficult of a concept, but it still can be error prone, so an app like this is handy to double-check your work (or I suppose to do it in the first place). There are some calculus and math apps that will do this and more, but they are usually a lot of money, so if you just need partial fraction expansion, this app will do the deed for just a $1.
