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...

DM50 is a faithful tribute to the golden era of scientific calculators, bringing the legendary HP-style experience to your iPhone with modern enhancements. Whether you're an engineer, student, scientist, or calculator enthusiast, DM50 delivers the power and precision you need, with the tactile familiarity of classic RPN entry and a crisp, authentic 132×64 monochrome LCD display. REVERSE POLISH NOTATION (RPN) A true HP-style RPN engine with a dynamic multi-level stack, stack lift, SWAP, ROLL and DROP. Once you learn the flow, complex calculations become faster and more intuitive. ALGEBRAIC MODE (CAS) Type expressions the way you write them: full operator precedence, parentheses and implicit multiplication (2π, 3(4+5)). Includes numerical derivatives ∂(f,a), definite integrals ∫(f,a,b), and nine memory variables (x, y, z, A–F) for chained calculations. EQUATIONS AND INEQUALITIES Solve linear and quadratic equations — complex roots included — and linear inequalities. MATRIX ALGEBRA Matrices up to 5×5 in a dedicated editor: addition, subtraction, multiplication, transpose, trace, determinant and inverse. MORE MATH MODES • 3D vector calculations • Complex number arithmetic • Base conversion: decimal, binary, octal and hexadecimal • Formula library with pixel-art diagrams, inspired by the classics • Constants library with common physical and mathematical constants SCIENTIFIC FUNCTIONS • Trigonometry with RAD / DEG / GRAD angle modes • Logarithms, exponentials, powers and roots • Hyperbolic functions, factorials and more AUTHENTIC EXPERIENCE • Pixel-perfect monochrome LCD rendering (132×64) • Classic keyboard layout with BLUE / ORANGE • Real-time status bar: clock, angle mode, modifiers and battery • Retro sound effects BUILT FOR POWER USERS DM50 is designed for depth. The layered modifier system exposes dozens of functions without cluttering the interface — just like the classic calculators it draws in A LITTLE FUN TOO A built-in dice game to take a break between calculations.
