## What is Calculator XplusY?

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.
