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.

Transcend Theory: This app is designed to generate random words. What the app does: The idea behind this app is to see if random formations of letters can create words and sounds of meaning. When you press the play button letters from an alphabet list will begin a random formation process at various lengths and intervals. These formations will be used to generate vocal sounds. Text transcriptions of these sounds can be used by turning on the Transcribe feature. The Filter feature of the app can be used to trim and "clean up" these audio clips to produce a more easily understandable interpretation. The result of this process will produce random words and vocal sounds. Settings: In the settings you will find a voice speed slider that can be used to speed up or slow down the voice sounds being produced. The reverb audio effect can be used to create a more spacious sound. A text log will store any text transcriptions you receive. The filter strength option of Low, Medium, and High will determine the amount of the audio segments that can be removed before regenerating a new audio clip. For entertainment purposes only.
