FX-991MS Scientific Calculator is a scientific calculator app that is aimed at students taking further education. It doesn't replace the need for a real scientific calculator, but it is a convenience tool, and the app may help you show your working when you write out your engineering and math homework or coursework.

The button interface matches other scientific calculators

The app’s GUI is built to represent how a scientific calculator looks and is laid out. Math students may find the app useful, but it is better suited for engineering students. Type in your data and it is displayed in large font on your phone, which is one advantage it has over a real scientific calculator since it is easier to see your calculations on a Smartphone than on a calculator display. Also, if you are working on a college/university project and you need to show your working, then you may be able to copy and paste your working onto a document, which is something that some real scientific calculators do not allow you to do.

A convenient tool

FX-991MS Scientific Calculator isn't and shouldn't be your primary scientific calculator because it is limited compared to the real thing. However, if you do not have a real one to hand, then this app may be the next best thing. The adverts are very annoying, and there are others out there that do not bombard you with adverts. Still, engineering students and math students may find this app useful, but they will still need a real one because you are not allowed to take mobile devices (Smartphones) into exams.
