## Review summary

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.
