## What is GenieCalc?

GenieCalc puts six everyday tools into one clean, dark-themed app. No account, no subscription — just open it and calculate.

Scientific calculator
Trigonometric, hyperbolic and inverse functions, logarithms, powers and roots, factorials, permutations and combinations, GCD and LCM. A running history lets you tap any earlier line to reuse it, and a D-pad moves the cursor inside long expressions.

Function grapher
Plot any expression in x over a range you choose and read the curve directly.

Currency converter
Live rates for 16 major currencies, plus any currency you add yourself. Added currencies survive a refresh.

Humidity tools
Convert between relative and absolute humidity, find the dew point, and compute saturation vapour pressure in hPa, kPa and mmHg — using the Magnus approximation.

Market indices
Track S&P 500, NASDAQ, Dow Jones, KOSPI, Nikkei, futures, gold, oil and crypto, with sparkline charts and a detail view.

Unit converter
Over 120 units across 11 categories: length, area, mass, volume, time, temperature, current, energy, power, radiation dose and radioactivity. You can define your own units too.

26 languages
The interface follows your device language, or you can pin a language in Settings. Numbers are formatted for your region.

GenieCalc is free and supported by ads. You can review your ad personalisation choices at any time from Settings.
