Please fix graphing!
I love this app. As a professional tutor / educator in algebra thru college calculus I use this app almost daily. but now I can't because it is constantly crashing when graphing square root functions, logs, rational functions etc. Never had problems before the shift to ios8 so I believe in you! I know u can fix this! Also, tried to use your "app support" but it takes me to a page that says file doesn't exist. Love to change Back to 5 star rating! Example equation that crashes (in the normal mode) is x/sqrt(x^2-9). Bizarre, but if I change the 9 to different numbers it will graph. Back to the 9 and it crashes. Many other equations too...

Would be five stars
However, since I've had iOS 8 I can no longer get landscape mode without half the calculator disappearing from the screen.......please fix for five stars!
iOS 8 issues
This latest update has issues when the device, (an iPad mini retina in this case) is turned landscape. This means that some of the objects, such as the text field in the calculator and the graphing area, are still as wide as they would be in portrait mode, leaving areas blank. Good app, keep updating.

Great app, needs one fix
This app is great and does everything it says it's supposed to do pretty much perfectly. I would recommend the addition of calculus functions like real graphing calculators have but not critical. There is one issue in the current build, however, when you mis-type a calculation you get an "unable to parse" message which is fine. But, when you tap that little message like you would a previous answer, the app immediately crashes and all previous entries are lost. Essential but not critical fix needed. Otherwise, great app!

Not open for customer feedback
This app could be really of a great value if there was a "contact us" access to allow the user to give feedback to the developer about app bugs and mistakes. For example, on the "Reference" selection at the bottom of the screen, we can access pages with useful math info. The problem is that, on some of those pages, there are mistakes and bugs, such as the one shown on the "Transform the Cat (linear)" page in the "Matrices" section. On this page, the app developer placed the matrix and the editing buttons right on the top, covered by the app title,
disabling the use of that matrix numerical buttons. ...Not too smart!

Table
Pretty sweet, but I think the table should include more than four functions
Finally, a calculator app that has plenty of functionality
Vector and matrix operations? Check. Crib sheet for integrals, differential equations, and all the other "how do I do that again?" math that I've forgotten over the years? Right there. I even like the mystery function game, helps reinforce the logic. After looking half heatedly at some other calculator apps I had almost given up, but this is going to get heavy rotation for my classes, and may wind up getting use after I graduate as well.

Student and teacher
This is my favorite go calculator. I have used HP's and TI's. What this calculator has over the others is touch editing. You can touch a previous solution and put it on the current equation so you don't have to retune the number. You can also see your equation and if there is a mistake you can tap on it and edit it. Graphing is easy and much clearer than other calculators I've used. I've used this app on an Itouch and iPhone which means I don't have to carry another calculator. It's not perfect, it once did not solve a complex trig function correctly( which other calculators also failed at). I always recommend this calculator to my students.

Awesome
Awesome. Just awesome!
Deserves More Than 5 Stars!!!
Brilliant App. Very easily worth the two bucks! I've been using this for three years, now a senior in high school. I used in in Geometry lots, finding great use for the triangle solver! It helped a ton in College Alg. with the trig functions not even supplied on a graphing calculator. I actually lost my T-i calculator & was able to substitute this app seamlessly. I'm now in calculus & am using it to graph inverse functions. The graphs are brilliant as the app itself, being color coded and having very easy zoom adjustment. Not to mention the trace application. This is an absolutely scintillating creation. Thank You.
