Calc² – Calculator

Replace your system calculator

$2.99 · Designed for iPad. Not verified for macOS.

Remember when your phone's calculator just worked? Before buttons got round and you started missing taps. Square buttons, zero dead zones. A calculator your phone should have had from the factory. Replace the built-in one and return to a square keypad where you won't make a mistake. One typo and everything goes wrong. A mismatched invoice, a ruined tax return, a board cut a centimeter too short. It wasn't you who miscalculated – your calculator betrayed you. Today's calculators pay the price for modern design: round buttons create dead zones on the screen. You tap between them and nothing happens. Or worse, a wrong number sneaks into your calculation without you noticing. With important math, one missed tap means a completely wrong result. Calc² takes you back to a time when operating a calculator was intuitive and every touch was one hundred percent certain. ◼ CERTAINTY WITH EVERY TOUCH Full square buttons from edge to edge, zero dead space. Wherever your finger lands, there is a button. Every tap is also accompanied by haptic feedback. No empty taps, no invisible typos, no ruined results. ◼ FOR CALCULATIONS THAT MATTER Taxes, invoices, budgets, or measurements – when a wrong number can cost you money, you need a keypad that is fast and perfectly accurate every time. Prevent a disaster before it happens. ◼ A DESIGN YOU ARE USED TO A clean grid, a truly black background, and a classic layout. From the first launch, you will feel right at home. ◼ SCIENTIFIC MODE With one touch, you switch to a fully featured scientific keypad – sin, cos, tan, log, powers, and roots. It also works in landscape mode. ◼ BUILT-IN UNIT CONVERTER Length, weight, temperature, and more. You convert everything right inside the app, without unnecessary switching. Currency exchange rates are updated every business day. ◼ CALCULATION HISTORY Go back in time and verify every step. Nothing is lost, no number goes unchecked. ◼ SUPPORT FOR 30 LANGUAGES The app automatically adapts to the language you use on your phone. ◼ PAY ONCE, HAVE IT FOREVER No ads. No subscriptions. No tracking. You pay only once and it is yours forever. When numbers matter, buttons matter too. Replace the calculator on your phone with one that never lets you down.
