## Review summary

PCalc Lite is a long-standing, capable calculator with strong RPN support and a reputation for quality. Users praise its clean, ad-free UI and customization options, plus split-view versatility. However, iOS 18’s removal of legacy widgets is a major usability hit, and some add-ons (Power Pack/Conversion Pack) don’t always work as advertised. There are recurring requests for formatting features like thousands separators. Overall it remains a trusted tool for power users, but modern platform changes and add-on issues are notable drawbacks.

### Pros

- Strong Reverse Polish Notation (RPN) support and functionality.
- Longstanding Mac-origin heritage and reputation as one of the best calculators.
- Ad-free experience on iPad and generally clean UI.
- Split-view support with scientific functionality and customization options (icon/view).
- Loyal user base and generally positive developer support.

### Cons

- iOS 18 removed legacy widgets; widget functionality is gone and users want an interactive widget again.
- In-app purchases (Power Pack / Conversion Pack) are sometimes not accessible or do not deliver advertised features.
- Requests for thousands separators and related formatting features are not implemented or reliably available across display and copy/paste.
