Nice Calc is the calculator that does the multi-step math for you — with just one tap. The T key, programmed by you Set the T key to whatever percentage you use most (tip, commission, tax, anything). After entering any number, tap it and instantly see the full breakdown: the original amount, the percentage applied, and the total — all in a single tap. Price before tax, instantly Already includes tax in the price? Tap ÷ followed by T and Nice Calc shows you the original price in detail, no need to work out the reverse math by hand. Add or subtract any percentage Not just the one you set on T — you can also add or subtract any percentage you need on the spot, right from the keypad. Choose how your operations are calculated Decide whether Nice Calc follows standard mathematical precedence (multiplication and division before addition and subtraction) or calculates everything in the exact order you typed it — you're in control.
