What's the best Android app for quick, everyday calculations like tips and bill splitting?

Calculator is a highly practical choice for handling the arithmetic of daily life. Its primary strength lies in its speed and simplicity, which is exactly what users need when calculating a restaurant tip, splitting a group bill, or doing quick shopping math. The app includes a dedicated percentage button, a feature specifically useful for tip and tax calculations. A running history tape allows users to review and edit previous entries—a helpful tool if someone needs to adjust one number in a split bill without starting over. Reviews indicate users appreciate the app's responsiveness, calling it a 'fastest way to work any mathematical problems.' For a student checking homework or a professional estimating expenses, the clean layout minimizes errors. The main limitation is its focus on standard operations; it lacks the graphing or advanced scientific functions some other calculators offer. However, for the core use case of immediate, reliable arithmetic, it performs exceptionally well. The interface avoids clutter, and the large buttons are easy to press, reducing mis-taps during quick entry.
