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.
Strange user interface
This was my most used application until the August 28 update. A graphic interface for a calculator should look like a calculator, not just a bunch of numbers and functions thrown on the screen. The layout is awkward to say the list. This is very disappointing and a perfect example of what happens when you try to improve what was already great.
Follow up, September 12, 2020: I took the developer's advice and gave the update a chance. I am now twice as disappointed. I have to wonder if the developers have realized that this "new and improved" revision has taken this application from a 4+ star review ranking to a 2 star. Who ever designed this new UI needs to take a vacation. This is not going to attract new and young users. In addition to the awful user interface, my screen does not display any menu, options or help screen. The keys are too small; unless your fingers are the size of a pencil, data entry is quite unpredictable and frustrating. I have no way of accessing any of the "new features" of the application. Perhaps this is a hardware compatibility issue. I am using a third generation iPad with IOS 10.3.3 which according to the developer is compatible with the app. All I can confirm is that I purchased an application that has been revised without notice to a point where it no longer resembles what I paid for and worst of all, may be incompatible with my iPad.
Fantastic functionality (pardon the pun)
This calculator does all kind of neat stuff. Without restating its functions (the app description does that well), I can say that as a scientist, engineer, and pilot, this calculator exceeds my very demanding expectations in so many ways. It makes beautiful graphs that are traceable and zoomable. It works with equations with ease, even complex ones. Calculus and statistics are no problem (again, pardon my pun) for this thing, too. I’d love it if it had a built in E6B, but other than that, it has everything! I totally recommend it to students, teachers, and professionals in STEM!
Great work devs!
