Excellent calculator
There are so many calculators to choose from and so many feel *almost* right. This one feels completely right and I recommend it.
Good App
My only comment is that when plotting polar coordinates it doesn't differentiate between r>0 and r<0, i.e. you can't tell where the graph actually exists based on what is shown, maybe make it a dotted line for r<0 or something, good apart from that though, very helpful
Works great, wide range of capability.
I haven't gotten to do all of what the app's features provide, granted I got it for its matrix calculator and was impressed by its possible uses, but disappointed in that it doesn't have a Reduced Row Echelon Form (often seen as "rref()" ) function for solving systems of equations using that method. Other than that, it's a great tool so far, and I think I might try to just convert my equations to slope-intercept and find their intercepts on the graph. Hope to see an addition soon! :D

Excellent program
Calculating and graphing are faster than expected for an iTouch. But there are processor limits - app pooped out (not a crash) at fraction of length of 0.8 when calculating 12th Overtone nodes for open pipes (using trig and hyperbolic trig functions). Comparison with known values showed good accuracy.
Cut and paste editing formulas does not work on my iTouch.
The paid version is handy for creating user constants esp. If many are used.
Editing area for formulas needs improvement. Besides cut and paste not working the scroll area is cumbersome since if you add at the end of a long formula it jumps to the top with every key press forcing you to keep scrolling down.
The min/max, roots etc work nicely and save time.
Overall, if you have the need for such a program, you should be satisfied with this app.

Best scientific calc I have found
I have tried all the graphing calculators, and there are a lot of them. I keep coming back to this one. All the extras features are great also. Absolutely happy!
The best
Had to refresh my math because of my teenagers. Could not find any other that i like. Thanks
Just found one error in the references. In "how to find the LCM with primes" the factorization of 6 is given as 2*3^2

Great App!!!
Hey this is such a great app recommended to all students. Or parents (that's me) helping their students!!!
Totally worth it!
At first I thought this would just be a waste of money for yet another terrible calculator..but this app really is the best one I've tried. Even better than my school calculators.
The fact that it has factoring, graphing, reference, and even games makes my life in math so much easier! The reference section taught me more in 10 minutes than my math teacher did in an entire week. Very helpful! Definitely invest in this app rather than a $60 graphing calculator..so many more features for a much better price. 5 stars👌 ⭐⭐⭐⭐⭐

Bug
This app is great however I found when using the implicit function like 2y +3x= 25 I can't go to the over side of the equation to change the zero to another number like 25 up in my example.i would really appreciate if this was fixed so I can use it as it is important in what I am doing.
Great app!
This is a very impressive and useful app great if you're studying mathematics at A-level or higher! The polar coordinates function is extremely fun to play around with too.
