Lots of Space for improvement

I am styding for an math exam and was looking for an app to aid me. I am at universaty and only looked into the "big" math stuff and the "childsplay" stuff.

- same of basic stuff, which you easyly forget but def to little for a ref
- sections are not homogen, for expample you expect a list of diffs/integrations which app has however they apper sepperat or with equations itself, which is inconsistent
- could be way more in this lists
- exapmles are only few and mostly only easy ones, not the intressting ones
- some topics missing like complex numbers
- no tip/tricks for most of the topic like what different easy way there is to do something instead of the normal way
- LA etc: way to little information and same must have equations totaly missing like det off an nxn matrix with n greater 3 or how to calc a signature or T and D of a matrix

All in all this app is pretty much worthless to me. I have about same amount of pages stuffed with equation, examples, tricks and alternative solutions just for LA & complex numbers. And they contain about twice as much infornation and I consider them a poor, just bearly enough summary which makes this ref pretty much worthless at least for higher edu. I also consider myself average at best at math and this ref didnt had any highlights what so ever in it.

I also think an real training app would be much better then just the ref here, but this is not a minus for this app, since this here is what it said it would be.
