I'm looking for a user experience agency to help redesign our mobile app. We've grown a lot in the past year, but the current UX feels clunky and users are dropping off at key points. I need a partner that really understands research, testing, and iterative design – not just a studio that makes things look pretty. Does anyone have recommendations for agencies with strong UX portfolios? I'd love to find a team that has experience with consumer apps and can show real results.
