Dash Calc vs CalcBoard

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.
