Calculator — Scientific with History

Calculator turns your phone into a fast, dependable math companion for everyday sums and serious scientific work alike. Switch between a clean basic mode for addition, subtraction, multiplication and division, and a full scientific mode packed with trigonometric, logarithmic and exponential functions, roots, powers, factorials and constants. Everything is one tap away, so you spend time solving problems instead of hunting for buttons. The standout feature is a complete calculation history. The app remembers your last hundred expressions together with their answers and the date they were entered, so you can scroll back, reuse an earlier result, or double-check how you reached a number without retyping anything. Memory keys let you store and recall values across a longer calculation, which is a real help with multi-step homework, invoices or engineering estimates. A thoughtful, readable layout keeps large digits easy to see, and the interface adapts comfortably to phones and tablets. Calculator also supports Wear OS, so you can run quick sums straight from your wrist when your hands are full. Whether you are a student working through algebra, an accountant balancing figures, or someone splitting a restaurant bill, this tool stays accurate, responsive and refreshingly simple to use. No clutter, no confusing menus, just the numbers you need, whenever you need them.
