The iPad is a device which is commonly used by students. The larger screen area as compared to a phone, facilitates reading and web browsing better than most phones. However, what happens if you need to do a calculation? For some reason, Apple did not include their stock Calculator app on the iPad.
Have no fear, though, there are several great options available to you which will be outlined below.
Note: I won’t get into the scientific functions of these calculator apps much in this review but they are definitely nice to have in an app for those of us in STEM (Science, Technology, Engineering, Mathematics) fields who want to do a quick calculation.
An alternative bare bones solution is Calculator. Please note, however, that the ads with Calculator can be quite annoying at times.
