User Reviews

Users praise the app for its intuitive interface and ability to display and convert numbers across Hex, Decimal, Octal, and Binary simultaneously, making programming and engineering tasks easier. Additional features like RGB color mixing are appreciated. However, consistent complaints highlight that switching modes clears inputs, the app cannot handle mixed-base arithmetic operations properly, lacks certain advanced calculation functions, and some minor usability issues like absence of backspace in color mixer and no clear purchase option.

Pros

Displays numbers simultaneously in multiple formats: Hex, Decimal, Octal, and Binary.
Simple and straightforward interface, making it easy to use for conversions and calculations.
Supports multiple layouts and converts between various number bases efficiently.
Includes additional features like an RGB colour mixer and programming-related calculations.
Reliable and helpful for programming, firmware development, and students in processors and controllers.

Cons

Switching between input modes or bases clears the current input or results, causing inconvenience during mixed calculations.
Does not support arithmetic operations involving mixed number bases (e.g., Hex plus Decimal) without resetting or errors.
Lacks some advanced features such as bit shifting, logical AND/OR operations, and progressive additions (like a+b+c).
Missing a backspace feature in the RGB converter, requiring users to clear and restart on mistakes.
No clear option to purchase an ad-free version or support the developers financially.
