User Testing:

We tested a variety of flows using different concepts to gain high level understanding of types of interfaces what users found intuitive. We could find out their pain points and what they wanted to see. The biggest problem with the product overall was when they actually use the app which they froze the card. We got some feedbacks that users do not want to set the dates each time they freeze their cards. Users were not familiar with the concept of "freezing card" in digital world, but they were familiar with "freezing physical card". We eliminated Task Manager concept since priority wasn't a problem for users when they purchase things compulsively. From the feedback, users use their banks' option such as "pause card". We decided to connect the product with a bank app.

User Testing:

Our main challenge was to figure out the categories of freezing cards. Should we block all the cards that users have? Or should we give users choices to choose their credit cards? And then, should we give users to block cards by categories or by stores? We found out compulsive shoppers tend to go to the same stores to spend their money, and if we categorize the choices, users will rather use another cards to purchase items.

User Testing:

We had to think about back-end system deeply as users had some questions of viewing stores instead of categories. Since there's only shame moment, users questioned about the reward moment. With A/B analysis, showing how many days they have froze the store was more effective than showing total money they have spent earlier. For friends' feed, we wanted to give interaction between users to share shame emoji, but they were confused of it. We decided to eliminate the feature, but to show what they have purchased.
