Fantastic, well worth the cost
My original review was bad because of glitch in an upgrade. Problem was immediately fixed and the app is Fantastic.
Addition to Review:
Have used for years, excellent and just keeps getting better. However, if check boxes could be added to the equations so you could plot only those equations and not have to clear the previously entered ones not wanted on plot. Never the less an excellent product.

Love this app !
Does practically everything you could possibly want with surprising ease, from simple calculations to more esoteric calculations. Absolutely essential for immediately checking out those problems that have been bothering you for weeks, but that the sudden flash of inspiration hits you when your out buying milk or something.
Two suggestions :
1) Add a "Contact Us" option to report problems or make suggestions.
2) Move or duplicate the Mode button from the equations screen to the graph screen and allow the displaying of formulae in more than the native projection.

Great Calculator!
This is an amazing calculator, which has helped me so much.
I would however like to point out, what appears to be a bug, when calculating something like: fact(12), it produces an an answer of, 479001599.99... Instead of 479001560, I find this problem doing some permutations as well as some combination.
Otherwise, great calculator!

Great App
This is the best graphing app out there, I have been using it for grade 12 calculus and works great for all problems.
It would be nice if there was an option to view vertical. Oblique and horizontal asymtopes though.

need to fix a little bit
I really like the app. The only thing I'd suggest is making it available to landscape view. You know it's annoying sometimes when you can only use it in portrait view. Thank you. Hope to see the new update soon.
perfect graphing calculator+
this is an incredible calculator app! it is capable of anything a TI-84 can do (minus the stats function) and includes an easy-to-use unit converter and an excellent reference guide to algebraic, geometric, trigonometric, and calculus rules and fuctions (and many, many more). the graph features settings for 6 different graph types (function, polar, parametric, etc) and is simple to use and can graph multiple equations using different colors for specificity. there are polynomial/quadratic equation and triangle angle/length solvers and lots of others i may never use but hey--they're there. great calculator and definitely worth the few dollars in place of a large, clunky, overpriced, 1-bit display texas instruments device

Fantastic program
List of constants is extremely useful, is powerful, intuitive and convenient for calculations on the run
Seriously Great app
Update March 2013: If you don't have this graphing calculator yet, and you're taking any math class of algebra, geometry, trig, calculus - you will love this app and you'll start recommending it to others, too.
Update, Jan 2013: More and more I love this app! I have recommended it to many students. It is very easy to use. Soooo easy to graph a function. Or several functions on the same screen to see where they intersect! Or to convert from oz. to kg. Or to refresh one's memory of geometry or trig.
My original Rave: I bought this math app (ver. 4.1) on Christmas Eve 2011. Have been playing with it on and off all Boxing Day. The triangle solver is great, it would be sooo helpful for a newcomer to geometry. This would be a wonderful present for someone starting into College Algebra and Trig or anywhere in the Calculus classes. Wish I had had this app this past semester while doing Calc III because the formulas are there, very handy, along with good explanations. The explanations (e.g., for complex numbers) seem very clear. I’ve been playing with polar graphs in the past hour (love those hearts and “roses” that one learns to do in Calc II) and they graph so nicely, black background or white, different color for each graph.

Great
This is a must have calculator. It has everything plus a lot more. I use it for fun but it would obviously be of great use to Engineering students or even math students. It is easy to use, even I can see the keyboard, the layout is very well thought out, and the vast majority of functions that could ever be needed are there. I have used this for calculations at work and also for fun things at home.

Finally a well designed scientific calc
I can't count how many calc apps I have tried in frustration. This is the first one that is intuitive and functional. The most often used keys and functions are the most accessible yet it is as capable as any. Like the built-in constants too.
