PCalc is the powerful choice for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator. It includes an optional RPN mode and multi-line display, a choice of button layouts, an extensive set of unit conversions and constants, a paper tape, multiple undo and redo, engineering and scientific notation, as well as support for hexadecimal, octal, and binary calculations. Includes an Apple Watch app, so you can calculate on your wrist!
Best calculator app
This is the best calculator app around. It is a combination of a good engineering/scientific calculator and a programmer’s calculator. The stack and RPN features are familiar and comfortable if you are accustomed to HP calculators. The app on Mac and iPhone work the same ways. It is nice to have the same app, regardless of whether I’m using the phone, pad, desktop, or laptop.
Fatal flaw for me
If I place the calculator in the background to collect figures, the calculator clears the register.. Argg If I want support I have to sign up for a social media site. Nope
Genius. Essential. Permanent home page spot.
Modifiable keyboard (main and 2nd), programmable functions, decimal/hex/octal/binary bases, keyboard/result formats for engineering , accounting, scientific, and others. Built-in conversions (pounds to ounces, miles to kilometers, etc). Constants (speed of light, local tax rate, etc). Used multiple times daily. Makes iPad/iPhone a true computer. First app I bought when I first got into Apple in 2004. Favorite of all apps. Does everything a calculator should do, and more. JT is a man with a great sense of humor. The world needs him. You need this app. 42.
Great
A great calculator, but I wish I could add a button to the control center or a widget. Please add that capability.
My absolute favorite app. Used daily. Makes a computer, a computer.
*ALL* math functions. Easily programmable keys: add your own. Constants and conversions. Numeric modes: decimal, hex, octal. Keyboard types: some are scientific, engineering, accounting; each with proper keys and result types. Selectable memory displays. James Thomson’s a genius developer with kind support and forward-looking updates. This is the first app I sought when I bought Apple devices and it has a prominent place on my Home Screen. It’s the ultimate answer: 42!
Hides history
No easy way to see history, which is the only reason I paid for it.
Best phone calculator as far as I know!
Wish I could still see an HP skin

Fixed a crash in the settings if you were using the 2013 app icons on iOS 17.
