A small, over the weekend project. I saw Telegram's generated QR codes and thought it would be cool to see how they do it. Turns out it's not that easy to create a custom, beautiful QR code image. I built the app though. A one screen app to create QR codes for URLs. It does some very basic checking for the enetered URL to see whether or not it's a valid URL.
I might dive into CIFilter and play around the names and filters until I get the look I want. But for now, this is all I have.
