## Description

Panecal is a powerful scientific calculator designed for engineers and students. It lets you display and edit formulas, checks syntax on input, and reuse past formulas to avoid re-typing.

Beyond basic arithmetic, Panecal supports base conversions (binary, octal, decimal, hex up to 32-bit), memory functions (M+/M-, A-F memory), a rich set of functions (trigonometry, logs, powers, roots, factorials, modulo), polar/cartesian conversions, and multiple result formats (Normal, Fixed, Sci, Eng). It also includes customizable decimal points and grouping, and a swipe-friendly, copy/paste-capable UI.

## Review summary

Reviewers praise Panecal for its readable layout, robust scientific functions, and useful memory/variable features, especially for engineers. However, the app is criticized for intrusive ads and an unattractive icon. A few users report stability issues. Overall, it’s a strong calculator with caveats about ads and branding.

### Pros

- Great, easy-to-read button layout and interface for a non-graphing scientific calculator.
- Feature-rich with many scientific functions and professional-grade capabilities.
- Memory and history features, including storing variables (A–F) and keeping input/results for easy verification.
- Intuitive and engineer-friendly; often compared to TI scientific calculators.

### Cons

- Ads are intrusive and sometimes misleading, with top-screen banners and suspicious ad content.
- Icon is unattractive/ugly, with some reviewers wishing for a cleaner icon.
