What Calculator OS 27 is for
Calculator OS 27 is a calculator for Android. The developer presents it as a simple, plain-looking tool for everyday sums, with a glass-style interface that the listing says is inspired by OS 27. It has two working modes, a basic one and a scientific one, so it fits both quick totals and more technical work.
The listing points to people who need a fast calculator for shopping, percentages and decimals, and to people who occasionally need trigonometry, logarithms or roots. Nothing in the listing narrows it to a particular profession.
Basic and scientific calculations
Basic mode handles addition, subtraction, multiplication and division, along with percentages and decimal numbers. This is the mode for totals, tips and discounts.
Scientific mode adds trigonometric functions, logarithms, powers and roots. The listing also mentions memory controls among its scientific features, so stored values are part of the scientific side of the app.
Unit conversion and recent results
Unit conversion is built into the calculator, so a conversion can be done in the same place as the arithmetic. The listing does not name the unit categories it covers.
The calculation history keeps recent results so they can be looked at again and reused in a later sum. The listing does not say how many results it keeps.
Display, buttons and settings
The developer describes large buttons and a clear display, aimed at making the numbers easy to read and tap. The glass-style design is presented as the main visual identity of the app.
A Settings screen lets you adjust preferences. The listing does not say which preferences can be changed.
What's new
- New Liquid Glass look for the mode menu, History and unit picker
- History grouped by day and month; drag up to see more
