ShopInPower has straightforward functionality and is easy to navigate for users. The technical requirements to use the app are simply a smartphone with a camera. The way it works is that when one shops alone, he/she can receive suggestions in real time from other app users in order to make a better decision. For example, if an app user goes clothes shopping and does not know if she should buy a dress, she can take a picture of her wearing the dress and upload it on ShopInPower. Other app users can view the picture and click the “like” button if they like it or “unlike” if not. They can also leave comments. If the girl ultimately chooses to buy the dress, a proportion of people who clicked “like” will receive “spoints”, which is a currency in ShopInPower. If she decides not to buy, a proportion of people who clicked “unlike” can also receive”spoints”. By accumulating spoints, app users can get brand discounts for their future purchases.
