Function Calc vs Calculator XplusY

A full-function, programmable, graphing scientific calculator designed to be very quick and easy to use, but with the added power of customisation. Tape display is visible while you type, and a swipe away from full screen view. Select and directly input any number from tape, undo or edit calculations. Easily create and use custom functions, store equations and useful numbers, use complex functions with multiple variables - fully programmable. Plot functions on a zoomable graph, export a high-resolution pdf copy. Dictate calculations and numbers for statistical analysis, with instant results. Completely free. • no adverts, no in-app purchases. • full set of scientific functions, unlimited nested brackets. • swipe to undo, step by step. • easily edit calculations and re-calculate. • optionally enter and edit calculations in standard maths format, rather than calculator order. • visible memory store. • tape output shows all calculations – swipe for full screen. • never type the same number twice – direct input from tape. • instantly convert between more than 120 different units. • zoomable text for easy reading and editing. • fully editable useful numbers page – store constants, conversion factors, commonly used numbers, tappable URLs or email addresses, or any text. • create, store and use functions for unit conversions or calculations, as simple as copy and paste. • dictate calculations, or lists of numbers for statistical analysis, get instant results. • create, edit and use complex functions with up to ten inputs or outputs – solve quadratic and cubic equations, calculate mortgage payments, compound interest, body mass index, triangles, the day of the week for any date, sunrise and sunset times and direction for any date and place, statistics (including normal, Student's T, Chi Square and F cumulative probability functions) and more – create or keep exactly what is useful, edit or delete what isn’t. 50 functions included. • fully zoomable graphing capability, plot one or two functions on a graph. Export PNG or high-resolution large pdf copies. • ideal for complex or repetitive tasks – custom functions reduce errors. • full help included.

Calculate faster. Think less. XplusY keeps every formula just one tap away. Create and save your own formulas, design custom buttons, and explore a growing library of predefined calculations across multiple disciplines XplusY uses a simple and powerful logic: “X” is the number you enter before pressing a formula button, and “Y” is the number you enter afterwards. This makes every custom formula easy to understand, predictable, and incredibly fast to use. Key features: - Custom formulas with dynamic input buttons - Reorder buttons freely to create your own layout - Two calculation modes – instant evaluation or step-by-step results - Display formulas during calculations for full transparency - Predefined calculations in finance, engineering, physics, geodesy, conversions, electromobility, and more - Real-time currency conversion with up-to-date exchange rates - Clean, intuitive interface with full Dark and Light mode support - Works offline for core calculations - History log for quick access to previous results - Swipe gesture to delete the last digit or clear input instantly - Customizable design – change button colors, background, and layout to match your style Whether you’re calculating percentages, converting slope values, or working with geodetic coordinates, XplusY lets you work faster and focus on results, not on switching between functions.
