back to portfolio


Stacks is an iOS app aimed to get people interested in the stock market. The app allows for people to bet on portfolio performance among their friends. It is currently being developed and the MVP is scheduled to be released some time in 2018. I worked on Stacks as a freelance designer during my sophomore year of college. I worked on the project over the span of a few months. I focused on validating user interest, gathering user research data, prototyping screens, and creating high-fidelity mockups for my client.



There is a large gap between being interested in the stock market and actually investing in stocks. This app hopes to bridge this gap in a fun way, by using fake money to compete against your friends in the stock market.


To make an engaging product that lets people compete with friends and learn more about the stock market.
