Ratings and Reviews
I use this calculator for many advanced and all of my variable based calculations for one reason - this calculator allows you to input the equation in its original form. For students, that means they can input their equations in textbook format father than a long string of numbers and variables with excess parentheses so the program can sort it out.
A couple things I would like to see. Needs and updated manual. Also, still can’t find the infinity button needed for some calculations. Also, would like the ability to tell it which variable to solve for. Right now it automatically solves for x but there are times i have multiple variables and need specific ones.
Also, I would like to complement this developer for always upgrading the existing app instead of trying to get people to repurchase a newer version as other app developers have been trying. I feel confident this developer won’t let his existing customers down and that says a lot these days.
I use this calculator almost every day if not every day. As a retired mechanical engineer, I spend most of my days doing research on about everything that pops into my head. The calculator uses numerical methods for calculating single integrals but does do numerical trigonometric solutions. The calculator also has plenty of memory slots. The shift key opens up other nice functions. It doesn’t allow for easy copying and pasting of results or equations that led to those results. Obviously, for people who really know how to do serious programming, Excel is almost infinitely better for calculating anything with the bonus of being able to print just about anything you like. I’ve written single cells with about 7 nested if statements using Excel. For a carry around calculator that isn’t programmable, this one is great and well worth the $4.99 or whatever it costs close to the aforementioned amount.
Great calculator, but ONE super annoying problem
It’s a great, feature filled scientific calculator, but they made the ridiculous decision to put the “options” button slightly overlapping the “0” button, resulting in accidentally opening the options frequently. It’s a bizarre decision, given that sliding the keyboard up a very small amount would solve the problem while only reducing the size of the output screen a negligible amount. Or they could have it overlap any button that isn’t used in approximately 1/10 of every equation I enter. Or just put it in the lower corner of the display area. I feel like they essentially places it in the worst possible location, and it makes me not want to use an otherwise great app.
