Calculator+ is a complete everyday calculator for iPhone, iPad and Apple Watch, built for quick answers, longer calculations and moments where history matters. Use it as a basic or scientific calculator for totals, percentages, discounts, tax, tips, fractions and multi-step work. Calculation history helps you review earlier steps, copy results, keep important values and continue without retyping the same numbers.
