A mess
This app is nonsense, I could solve one problem with it. I expected better I need a refund.
Disappointing
Answers given were not helpful at all, especially the graphs. Tried using it on some of the most basic problems and this calculator failed on every single one. Don't bother with this one
Do not buy.
This app only does about half of what the original wolfram alpha does. Buy the original app.
Just been ripped off
Save your two bucks
Wow did I get ripped off
Wolfram alpha is a good web site and calculation engine. And the iPad version is worthwhile, if just barely, because you get a little better iOS interface and keyboard. But after that, nothing. I saw nothing related to pre-calculus, no reference material, no worked problems, no templates. this little app adds no value at all to me, and only 1.99 to W-A. I am embarrassed for their sake.

A+
excellent, far more useful than a graphing calculator. Will reccommend
Bad App
This app is confusing to use. Poor design and it keeps crashing. Save your money.
Precalculus stopped working!
The App suddenly stopped working on BOTH my iPad AND iPhone. Please, fix the problem!
Stopped working
Today this app just completely stopped working. Will not respond at all.
It's more of an answer key
It might be my fault. But I expected this app to be more of "how to do the problem" app but i found it to be just a little behind an answer key. The app needs more development. The only difference between this app and WolframAlpha app is that this one gives like a step (without explanations) to the solution and the rest of the steps are left to your imagination. I would rather buy the solutions manual or just go through the course without this app. This app has not not helped me with precalculus in the very least.

Precalculus is *STILL* the Most Important Math Course
The only way to succeed in a math career is to excel in precalc ... And this app will help as a tool for review to make sure you have it right ... if you work hard, this app, as well as the algebra app and the WolframAlpha app will help propel you into calculus with a good math background ... otherwise, change your major to Shakespeare :) If you do continue in math and want to polish a few of the rough edges, a few hours spent within Wolfram MathWorld will be very productive, not to mention that it may be addictive.

Amazing Resource
This app is an essential resource. It allows for easy computation while leaving room for learning.
