Corona isn’t just for building games, and it doesn’t require a lot of complex code to build something useful. We present to you Corona Calculator, a simple calculator built purely in Corona SDK. No images are used — just 100% Corona/Lua code.
If you want to check it out for yourself, you can download the app from Google Play or Amazon (coming soon to iOS) and see this simple Corona app in action. If you’re curious about what it took to make the app, download the source code and learn how we built it. The code is open source under the MIT license and is free for you to use and modify.
