This is the pinnacle of Calculator apps on iOS. The only way could be better is if I could play games on it, like I did on my old Ti-85 in high school 😉 (check out “About by PCalc“ for some delightful surprises) I’ve customized my calculator layouts very nicely, though I do wish I could more easily synchronize those (and other settings) between iOS and Mac versions. Bottom line: If you ever wished the built-in Calculator app could do a bit more… Or even a lot more, then get PCalc!

Pcalc has been a staple on every iOS device since it was first released. If I had any complaint, the modern LCD font is too bold. We need a standard version of this LCD font too…just sayin. ツ

What did you do with my calculator? I loved this app. The latest update completely changed the look that I now can’t get back. Why?!?

Improved support for iOS 26, iPadOS 26, and watchOS 26. Added some icons that are always light or dark, regardless of system setting. Added dark and tinted variants for the "2016 Earth-2" icon. The "Chalk" and "Wood" icons have come back, due to popular demand. Fixed a problem with the tape sidebar not appearing. Fixed a problem with button text being too small or too big.
