## Description

Smart Calculator Pro is a practical calculator that keeps track of what you&#39;ve been doing. Every calculation stays in a running history, so you can scroll back, tap any line to reuse the result, and edit a previous entry when you catch a mistake. Memory buttons work the way you&#39;d expect from a desk calculator: store, recall, add, subtract, clear.<br><br>The interface is split into three simple modes. Basic mode is a clean, large-button layout for everyday math. Scientific mode adds trigonometry, logs, powers, constants and parentheses with proper operator precedence. The unit converter covers the conversions people actually use — length, weight, temperature, area, volume, speed, time and currency presets you can edit yourself.<br><br>A lot of attention went into details: big tap targets for thumb use, a subtle animation that confirms each input without being distracting, and a generous undo so accidents don&#39;t cost you your numbers. Results are copyable with a single long press. Keep the history as a running log for a project, or clear it in one tap and start fresh whenever you want.
