About this app
TextCalc is a notepad that quietly does the math for you. Write the way you think, in plain sentences, lists, and numbers, and the answers appear right beside the line as you type. No equals key, no separate calculator, no clutter. It's the fastest way to work out a quote, split a bill, plan a budget, convert units, or check a currency without ever leaving your notes. HOW IT WORKS Just start typing. Put math anywhere in a line and TextCalc evaluates it live: • Arithmetic with +, -, ×, ÷, powers, parentheses, and percentages • "15% of 200" and "200 + tax * 100", written the way you'd say it • Variables: write "tax = 0.1" once and reuse it anywhere below • Running totals that update the moment you change a number CONVERT ANYTHING, INLINE Type "120 cm to m", "5 kg to lb", or "100 f to c" and get the answer in place, across length, weight, temperature, time, volume, and data. Live currency conversion uses up-to-date exchange rates and keeps working offline from the last snapshot.
