Slide to Add Interaction (GIF Animation)

This was made quite a while ago. I was helping to improve the whole UX and interaction design for the Carrefour shopping app. Client and I decided to change that slide gesture from the last shot into a slide-to-add gesture: when sliding a item in the product list, the item will be added into shopping list (the blue button at bottom). And at the app's first launch, the shopping list button and one of the item will bounce a bit to implied that they are interactive.
