User Reviews

PCalc is lauded for being a powerful, highly customizable, and reliable calculator suite across iPhone, iPad, and Mac, with features like RPN, tape, and conversions. Reviewers repeatedly praise its depth and one-time purchase value. Common drawbacks center on UI/readability issues after updates, removal/breakage of widgets and quick-access features, licensing costs for Mac, and imperfect cross-device sync.

Pros

Powerful, feature-rich calculator with RPN, memory, tape, conversions, constants, and programmable keys.
Extremely customizable UI and layouts—colors, themes/skins, button shapes/sizes, and per-device layouts.
Reliable, long-standing tool trusted by engineers; capable of replacing complex workflows (e.g., memory and functions for calculations).
Excellent cross-device support across iPhone, iPad, and Mac, with flexible layouts and orientation handling (split-screen/slide-over).
Strong value as a one-time purchase with no ongoing subscription.

Cons

Readability and accessibility issues due to bright, distracting themes and lack of high-contrast text; updates can worsen readability.
Widget/Control Center support has been removed or broken in newer iOS/iPadOS versions, reducing quick access and convenience.
UI updates/regressions that alter the look-and-feel and sometimes cannot be reverted to previous versions.
Mac/iOS licensing friction: separate purchases for Mac and iOS, with some reviewers perceiving the Mac price as high.
Cross-device sync of layouts/settings is not as seamless as some users would like, making it hard to keep configurations in sync across platforms.

Recent reviews

PCalc is powerful, but the UI is a mess. Themes are bright and distracting, and there’s no way to get simple high-contrast text across the keypad, tape, and buttons. Fix one area and another becomes unreadable. Basic readability shouldn’t be this hard.
