Eunite: Collaborative trip planning app

I started with a hypothesis: existing travel tools are built for solo or couple travelers, and completely ignore the social and logistical complexity of planning with a group. I ran expert interviews, friend conversations, and a 14-person survey to validate it — and learned that the biggest pain points weren't just logistics, but transparency and consensus. Nobody wants to be the person who shoots down someone else's idea. That insight directly shaped the rating system — designing it around how you feel about something rather than voting yes or no. From there I mapped three distinct personas based on planning involvement level, built user flows across three devices, and deep dived into state explorations for edge cases like suggestion cards, group rating states, and real-time alerts.
