Even if I was satisfied working in landscape mode, there’d be things about the scientific layout that annoyed me: I prefer to work in portrait mode, which means all the “advanced” features-like squares and square roots-are hidden. Personally, I could never go back to the Apple calculator. If this fits your needs, you’re done searching and you’ve saved yourself a few bucks. That switches to a scientific calculator in landscape mode. Have some pride.Īpple’s calculator is a basic five-function 1 calculator in portrait mode It can’t be just a four-function calculator. I enjoy watching MyScript Calculator turn my handwriting into an equation, but that’s no way to get work done. Calca is an interesting idea, and I can see it being very useful on a device with a keyboard, but typing out calculations on an iPhone is inefficient and having extra rows of keys leaves too little room for the display. If I’d needed internet access to do a simple calculation, my clients would’ve started looking for a new engineer. I’ve been in meetings in downtown Chicago where I couldn’t get a cell signal to save my life. I like Wolfram Alpha, and it can do things that none of the calculators I’ll discuss here can do but you can’t depend on always having a good connection. It cannot rely on an internet connection. Apps like Graphicus can be very useful, especially to students, but our focus here is on efficient calculation, not visualization. Even if an app has no obvious bugs, if it isn’t updated periodically, it won’t be able to take advantage of new phone features like the bigger screens of the iPhone 6, 6 Plus, and their successors. Apple’s built-in calculator couldn’t even deal with π properly when version 2.0 was released. You’d be surprised at how many bugs can crop up in a calculator app. There are several apps that slavishly imitate well-known, even beloved, physical calculators, and therefore don’t take advantage of the flexibility that an app provides. A physical calculator has restrictions-in button layout, for example-that a calculator app shouldn’t have. This is not a complaint about skeuomorphism. It has to be a real app, not an emulation of a physical calculator. Here are my criteria for pruning the vast tree of calculator apps down to just three that are worth your attention: By joining the Sweet Setup community you’ll also get access to our other guides, early previews to big new reviews and workflow articles we are working on, weekly roundups of our best content, and more.

But even after eliminating those from consideration, there are still a ridiculous number of calculators available for the iPhone. A lot of these are special-purpose apps-tip calculators, weight-loss calculators, mortgage calculators-that we’re going to ignore here.
Unfortunately, a search for “calculator” on the App Store turns up over 2,000 hits. A good calculator app on your phone can save you a lot of time. And, when the calculator is an app on the phone that’s always with you, the efficiency is even greater. Calculators are tremendously efficient when the work requires only a handful of operations rather than hundreds. For lots of calculations, setting up a spreadsheet is just too fiddly and time-consuming. But that doesn’t mean calculators are dead. Spreadsheets and systems like Matlab and Mathematica have taken the place of both the calculator and the pad of paper when the analysis gets deep and complicated. Nowadays, I wouldn’t dream of using a calculator that way. In those days, hours of repetitive analysis would be done with a calculator sitting next to a pad of paper-one for running the numbers, the other for keeping track of the logic. When I went off to college, electronic calculators had only recently supplanted slide rules as standard equipment for engineers and scientists, and professors were lamenting their new students’ pathetic underappreciation of significant digits.
