The goal with Rooster's Den was to better understand how fastfood chains like McDonalds and Starbucks create mobile interfaces in order to encourage user retention. After researching and testing various fastfood mobile apps from start to checkout, I found that there were many shared traits between them. For example, most mobile fastfood apps have some kind of reward system that encourages users to order online for deals and rewards. Another trait many of them shared was that most options and buttons to click on will inevitably funnel users into the menu, which then takes you to check out once an item is added; this makes it difficult to get lost and potentially lose user retention due to frustration..
