## Description

The **Boolean Algebra Calculator** is a powerful and intuitive Chrome extension designed to simplify and accelerate calculations in digital electronics. Whether you're a student or an electronics hobbyist, this tool offers step-by-step Boolean function minimization using methods like Quine McCluskey, along with detailed explanations of each Boolean law applied.

Key features include generating truth tables and interactive Karnaugh maps (KMAP) for up to 5 variables, automatic circuit generation with various logic gate options, and conversion capabilities between binary, hexadecimal, octal, decimal, and up to custom bases 36. It also supports arithmetic calculations across bases, code conversions (like binary to grey code), and canonical SOP/POS generation, all within a clean, user-friendly interface enhanced by custom keyboards for easy input.

Unlock advanced features using in-app currency or purchases, and benefit from comprehensive in-app help and prompt support. This extension is the ideal companion for anyone learning or working with Boolean algebra and digital logic design.

## Review summary

The Boolean Algebra Calculator app is appreciated for its usefulness in digital electronics education and ease of use. However, many users report disappointment due to key features being locked behind paid upgrades which often fail to unlock properly. Users experience issues with invalid expressions, poor UI/UX, and limitations in copying generated logic circuits. While it holds potential as an educational tool, reliability and payment issues significantly hinder user satisfaction.

### Pros

- Very useful for Digital Electronics and Boolean Algebra learning.
- Makes Boolean algebra work easier and more understandable.
- Includes helpful features like logic circuit generation and Karnaugh map functions.
- User-friendly and useful for students and professionals.

### Cons

- Many essential features are locked behind a paywall, limiting usability in the free version.
- Paid upgrades often do not unlock features as promised, causing frustration and claims of fraud.
- App crashes or returns 'invalid expression' even for valid inputs after upgrading.
- User interface and user experience are poor, with awkward custom keyboard and confusing navigation.
- Logic circuit outputs sometimes overflow the screen and cannot be copied or shared easily.
