Terrific.
Love all its features. Especially the way it keeps a history of calculations that you can then tap to copy into the current calculation.
Best App in the App Store
I use this app more than any other app on my iPad. I'm a high school math/physics tutor, and this is my go-to calculator. The interface is intuitive, and there are great extras like the triangle solver, the polynomial solver, and a nice reference section. The way the graphing function works is fabulous for demonstrating concepts to students. The developer, William Jockusch, is extremely responsive. I once emailed him to ask about a feature I thought would be good, and he literally added it overnight and updated the app. Get it - you won't regret it.

Love This Calculator
Had the free version for a really long time and realized that there was no other calculator out there that had the same feel as a multi-line graphing calculator so I decided to drop the $2.99. The free version of this calculator has been my go-to for a very long time so it's nice to have the full version now. I love all the included extras, this is much more than just a calculator and it is a must own for anyone doing real math on their cell.

Great App! No 3D Graphing Support Though
This is a great app, and has been very useful for my studies. Unfortunately there's no support for graphing in three dimensions though...
Simple and capable
I'll be honest, it took me a little while to acclimatise to the way it all worked but once I did it's been a massive help.
I'm doing a science degree in physics and it's just so handy to have a proper calculator with me all the time like this one.
Also, because it's on a phone I think it's nicer to use than many traditional graphics calculators. At least, it's better than my old ti thing.

Great graphing calculator
Fantastic application that makes good use of the ipad interface. Have used graphing capabilities to explain differentiation and integration to my son in yr 12. Heaps better than classpad. Reference section is handy. Lots of capability that we have not used.
ABSOLUTELY BRILLIANT BUT...
... It always crashes when I go onto reference and just before it gets into an explanation it crashes
Worked perfectly before
Please fix it, otherwise, BRILLIANT app (5 stars)

Great App
This calculator is capable of doing more than it appears.
A great App
For the price this is a brilliant program. I wish I had had this when studying for my degree.
No Paste, No Copy
I very much like the overall design of this app. However, there are two simple and important things it does not do.
I have not found any way to paste something from the clipboard into an expression.
I have not found any way to copy a result onto the clipboard.
Thus, I cannot make this app work with other apps.
Compare this app to GraphCalc. The iOS clipboard operations [Paste], [ Select Select All Paste], and [Cut Copy Paste] all work in the expression input area of GraphCalc. A result (or an expression) can be copied from the history into the expression input area. From there it can be copied onto the clipboard.
I also prefer the larger expression input area of GraphCalc.
I do prefer the larger keys in this app to those in GraphCalc.
I dislike having e and E on the same key. I dislike having i on the decimal key.
Constants at the top of the cnst table are available with two taps, which is a good design. Leave i in that table and add pi and e. Take i off the decimal key. Take e off the E key. Ether leave pi on its key or replace it with i to emphasize that this calculator does complex numbers.
I would like to have a better way to communicate with the developer of this app than by leaving comments in a review on the App Store.
