### 1/5 — Mistake alert

*2014-12-13, version 1.0*

Be careful: there are tons of mistakes in this app!

For examples:
1. Integral of tan x dx = - ln abs(cos x) + c
2. Integral of Csc x dx = - ln abs (Csc x + cot x) + c

### 3/5 — It's alright, but be careful of typos...

*2014-03-29, version 1.0*

Uh, guys??  The quotient rule uses a MINUS in the numerator!  This would be a great alternative to carrying around notecards, but I have to question everything after spotting this error.  Will you fix it, or is it fixed in the 'paid' version?!

### 5/5 — EXTREMELY helpful!!!!!!

*2012-05-09, version 1.0*

This app seriously helped me soooooo much in studying for my ap calculus exam (which is tomorrow, yuck!). Before I got the app I couldn't remember squat about a lot of the trig integrals and now I've got them memorized! Plus, this app is helpful in reviewing calculus rules. I was able to study calculus anytime, anywhere without carrying around a bunch of notes. :) Also, this app is free!!! It could be even better if there were memorization games included but it's still a great app for any calculus student. :)

### 5/5 — Great!

I love it!
