Change Calculator vs OYO Communities

Change Calculator tells you what to hand back, the moment you tap the cash you were given. Made for the market stall, the yard sale, the bake sale and the school fair: anywhere you take cash without a till. It also works the other way round, so you can check that the cashier got it right. HOW IT WORKS 1. Type the bill. 2. Tap the coins and notes the customer handed you. 3. Read the change. The app also shows which coins and notes to give back. WHAT'S IN THE DRAWER • Over 150 currencies, each with its real coins and notes. The app starts with the currency of your device; switch with one tap. • Hide the denominations you never see, so your drawer matches your stall. • Undo a wrong tap, reset for the next customer, haptic feedback on every tap. • Dark mode, and a layout made for iPad. • Works completely offline. PRIVACY No ads, no accounts, no analytics. Nothing is tracked and nothing leaves your device. CHANGE PRO A single optional purchase that supports development and removes the occasional upgrade prompt. Everything else is included for everyone.
