I used the Sketch "Delicious" free UI Kit for a food recipes app. It includes 11 pixel-perfect screens. I just added Proto.io interactions and created a great prototype! This Delicious UI Kit was designed by Robert Anitei Sketch source: https://www.sketchappsources.com/free-source/1765-delicious-ui-kit-sketch-freebie-resource.html

I'm going to give you an explanation of the best modern football formations. A football formation is a number set that describes the positions of players on the field. It determines how many players play on defense, the midfield, and the frontline. The first number always describes the defender, and so on. For example, a formation like 4-3-3 plays with four defenders, three midfielders, and three forwards. The goalkeeper is never mentioned in a football formation. Most formations are described in three numbers but four- and five-rank formations are also possible. This is created in Proto.io using States and States Animations.

This prototype showcases a new Proto.io feature called Gradients, it’s a new way to create and animate gradients straight in Proto.io. You can now make your UI pop with vibrant linear or radial colors, and bring to life with beautiful animations.
