No subscription. Try the full app free for 7 days, then choose a one-time Lifetime Unlock to keep calculating. No ads or other in-app purchases. History that sticks around. Name calculations you use often, filter to find them later, or pin one to compare against while you shop. Deleted entries can be recovered for 30 days. LIVE RESULTS See instant results as you type—no need to press equals. Dash Calc follows the standard order of operations: 1 + 2 × 3 = 7 Need a different order? Add parentheses: (1 + 2) × 3 = 9. One smart button handles opening and closing parentheses for you. EDIT EXPRESSIONS Tap an expression to edit it—no backspacing through long calculations. • Edit any number or operator in place • Keep long expressions readable without scrolling • Undo with a shake or the toolbar button RESULT FORMATS Show results as numbers, your region’s currency, or percentages. Calculate 1 ÷ 4 and switch to percent to see 25%. Saved calculations keep their chosen format in History. Very large and very small results automatically use scientific notation to stay readable. TIPS, TAXES & DISCOUNTS Add a tip, include tax, or take off a discount. See the amount being added or subtracted as you type. 16.85 + 20% = [+3.37] 20.22 279 − 25% = [−69.75] 209.25 History keeps the complete expression and result. POWERS & ROOTS Drag the keypad up to reveal more keys: Ans, π, 1/x, nth root, ±, √, x², and x^y. Drag down to see more History. √144 + 6 = 18 2 × 3² = 18 ³√27 = 3 Tap √ on a number you’ve already typed to take its square root without restarting the expression. Use Ans to pick up where your last calculation left off. THEMES & CUSTOMIZATION Choose from seven color themes: Classic, Cranberry, Denim, Grape, Grass, Pumpkin, or Violet. Every theme supports light and dark appearances, plus Increase Contrast. Customize the keypad too. Choose a standard calculator layout (7-8-9 on top) or a phone-style layout (1-2-3), with round or square buttons. ACCESSIBILITY Built with VoiceOver users in mind, with clear navigation, descriptive labels, and braille display support. Text size and Increase Contrast settings are respected throughout. BUILT FOR EVERYDAY MATH From tips and discounts to powers and roots, Dash Calc focuses on everyday calculations. Trigonometry and logarithms aren’t included. Designed for portrait use. ABOUT THE FREE TRIAL Dash Calc is free to download and includes a 7-day trial of the full app. Start the trial whenever you’re ready by completing a $0 purchase in the app. There is no automatic charge when the trial ends.
