Dec 2017 4-week Group Project

My Role: User Research, Wireframing, Interaction Design, UI Design

Venmo is an app that simplifies money transfers between individuals, allowing consumers to quickly pay people in their networks for any reasons. 


During our research process, we identified some pain points through in-depth interview with the existing users. Based on the pain points, we did the iterative design to improve the experience around the transaction flow.

"Just Venmo me"
  • Require user's minimal cognitive load to finish a bill transaction. 

  • Make payments feel quick and easy like sending a text message. 

  • Help user feel in control of their payment experience.

  • Give user the right amount of information at the right time.

Iterations Breakdown

Home View

1. Show user-related transaction history section by default once user enters the app.
2. Visually emphasize the transaction section, and divide it into two different flows.
3. Modify the layout of each transaction to enhance the social feature.


1. Emphasize recipient info and bill amount to visually reduce the probability of error.
2. Add emoji shortcut to help user save time on comment, and add juiciness to the experience. The recommendation of Emoji will be based on user's transaction history and bill amount.


1. Assist user to split the bill efficiently by simplifying the calculation process.
