UI a bit too big
It’s a great calculator, but I find that the UI is too big in portrait full screen and too small when it’s used in a slideover window. Would be better if the space was utilized more efficiently on an iPad. That would also make room for hyperbolic functions on the keypad rather than having to go into the catalogue just to access them.
Also, landscape mode is currently just the portrait window with big borders on either side. That space could be used for more keys or perhaps have the graph on one side and the calculator on the other.
I use this author's rock solid financial calculators almost every day. This 83 seems to be just as dependable. Includes lots of extras, super fast graphics and accurate calculation. His calculators including this one are well designed and implemented and are a pleasure to use. What more can I say!!
Gets me fired up for math class
Graph n calc changed my life it was like AA for me it truly brings out the best in you. Changes the way you truly look at math and life, so much love for the creator and D2L for helping me find my way through addiction, abuse and sexual intercourse
