NerdCalc is a binary, hexadecimal and decimal calculator that displays all three number bases at the same time. With NerdCalc, you can quickly switch which base you are inputting and the result of your calculations is always updated for all three bases, no matter what the current input mode. NerdCalc supports both unsigned and 2’s complement, to allow for negative numbers, and can perform basic arithmetic and logic operations as well as bitwise shifting. Enjoy!
PyCalc
This app offers a revolutionary approach to mobile calculations, allowing users to view and edit entire equations at once. It leverages the power of Python 3.11.1 for advanced functions, symbolic math, and financial analysis, making complex computations accessible on the go.
- Real-time editable calculation view
- Python 3.11.1 interpreter
- Programmable scientific calculator
- Support for matrices and fractions
- Built-in Python packages (math, sympy)
- Financial analysis functions
- Symbolic math capabilities

What most people love first about PyCalc is that they can see and edit their entire calculation all at once. It's a simple idea but it makes a huge difference in the kinds of calculations people end up doing on mobile. But that just scratches the surface of PyCalc's features and capabilities. The more you learn, the more you'll see how easy it is to do calculations that were always too hard before on mobile. Jump in and learn a truly better way of calculating. Basic features: ● A new and better approach to mobile calculation ● A cleaner interface for complicated calculations than traditional calculators ● Calculate by voice ● A history list keeps track of your previous calculations ● Functions built in for a huge range of applications ● Multiple keyboards optimized for different use cases Advanced features: ● Based on the Python® language, with access to the power of a full Python 3.11.1 interpreter ● Programmable scientific calculator: An editable startup.py script allows you to define your own functions for easy access later ● Streamlined support for matrices and fractions ● Many standard Python packages, such as: math, statistics, random, sympy, mpmath, fractions, decimal and datetime ● Basic financial analysis functions: pv(), fv(), npv(), pmt(), etc. ● Built-in support for complex numbers ● Symbolic math via the sympy package ● http/https queries via requests package ● Much, much more...

Verdict
The clearest difference is update cadence: PyCalc at every 2 weeks against NerdCalc's every 19 months. PyCalc also leads on review sentiment (100% vs 83%) and rating (5.0 vs 4.8). NerdCalc's advantage is ratings volume (183 vs 15). On price, ads, in-app purchases and monetization model there is nothing between them.
