Had some time available and wanted to play with user interface design, so I thought of a simple app that lent itself to that. Coding was roughly 8-10 hours for the whole thing, then another 15-20 hours to take the pictures (homemade studio, iPhone for camera, Gimp to edit). Looking forward to your feedback, and I have promo codes available for anyone that wants themhttps://itunes.apple.com/us/app/simple-knot/id593421479?mt=8
