Calculator OS

Calculator OS brings everyday calculations and scientific functions together in a clear, glass-inspired interface.

CALCULATE AT YOUR PACE
Enter a complete expression, review it on one line and tap equals for the answer. Long expressions scale to fit, with horizontal scrolling when needed. Continue from a result or repeat the last operation with equals.

SCIENTIFIC TOOLS
Work with parentheses, powers, roots, logarithms, trigonometric and hyperbolic functions, factorials, constants and memory. Choose degrees or radians and use portrait or landscape layouts.

UNITS AND CURRENCY
Convert between 12 groups of units, including length, mass, temperature, area, volume, speed, time, angles, data, energy, power and pressure. Currency conversion supports 12 currencies, including USD, VND, EUR and JPY. Exchange rates are provided by Frankfurter, with a displayed data date and a local cache. Internet access is required to obtain fresh rates.

KEEP TRACK
Review recent calculations, reuse a result and copy expressions. Create typed math notes with variables, line-by-line answers and a 2D function graph. Notes, history and appearance preferences are stored on your device.

MAKE IT YOURS
Switch between light and dark appearances. Use the basic calculator for everyday work, or open the scientific layout for additional functions.

The current interface is in Vietnamese. Math Notes uses typed text; handwriting recognition is not included. Displayed numerical results use finite precision.

ADS AND PRIVACY
The free version includes Google AdMob banner ads. Calculator expressions, history and notes stay on your device.
