About this app

Step into a haunted graveyard every time you need to do math.

GhostCalc is a fully-featured calculator wrapped in a spine-tingling horror theme — drifting ghosts, rolling fog, a pale moon, and tombstones set the scene while you calculate. It's not just a pretty face either: underneath the atmosphere is a genuine scientific calculator built for everyday use and serious number-crunching alike.

WHY YOU'LL LOVE IT

👻 Atmospheric Horror Theme
Watch translucent ghosts float and bob across your screen, fog drift past a glowing moon, and lightning flicker in the distance — all animated live, no static wallpaper here. Every tap comes with a satisfying press animation and haptic feedback.

🧮 Complete Calculator Functionality
Handle everything from quick everyday sums to advanced scientific work:
- Basic arithmetic: addition, subtraction, multiplication, division
- Percentages and powers
- Square roots and factorials
- Trigonometric functions: sin, cos, tan, and their inverses
- Logarithms: log (base 10) and ln (natural log)
- Parentheses for complex expressions
- DEG/RAD toggle for angle calculations

📜 Persistent Calculation History
Every calculation you make is automatically saved — right down to the expression and result. Close the app, restart your phone, come back a week later: your history is exactly where you left it. It's only ever erased when you choose to "banish" it yourself through a clear confirmation step, so you're always in control.

🎃 Built for Everyday Use
Despite the graveyard dressing, GhostCalc is designed to be genuinely usable day to day — clear, legible display, logically laid-out keys, and smooth performance so the spooky effects never get in the way of getting your answer.

WHO IT'S FOR
Whether you're a student who wants exam-time math to feel a little more fun, someone who loves Halloween season year-round, or you just want a calculator app that doesn't look like every other calculator app — GhostCalc turns a mundane daily task into something memorable.

No ads interrupting your calculations. No unnecessary permissions. Just a calculator that happens to be haunted.

Download GhostCalc and let the spirits help you crunch the numbers.
