Usability testing on native — refining MetLife's redesigned Android and iOS apps for millions of customers.
Key contributions: planning, facilitating, and driving outcomes.
MetLife, a global insurance company, was building a digital platform to help millions of customers in Turkey manage policies and pensions. I led usability testing and design improvements to ensure the platform was clear, scalable, and customer-friendly. This project required consolidating 70+ features into one cohesive experience while balancing customer needs with business requirements.
During the usability evaluation of MetLife's redesigned Android and iOS apps, the goal was to uncover which design elements supported users effectively, and which created friction. Key questions included:
These insights directly informed subsequent design decisions — prioritizing clearer navigation, refining terminology, and improving the discoverability of high-value features.
Defined user tasks, personas, and success criteria.
Moderated 10+ usability sessions, created test scenarios, and tracked performance.
Analyzed Maze data and survey results, refined flows based on insights.
I conducted test with 6 users.
I conducted three internal pilot sessions to validate the testing method, timing, and flow. These helped refine materials and ensure smooth facilitation before launching the full study.
Moderated a total of six usability tests with end-users, observing behaviors, pain points, and workarounds across both Android and iOS apps.
Collected both qualitative and quantitative data, grouping findings into themes and assigning severity ratings. We identified friction points in critical user journeys, as well as opportunities to strengthen clarity and consistency.
Partnered with stakeholders to prioritize issues using feasibility, viability, and desirability criteria. Produced a comprehensive usability report that guided design refinements and influenced the next iteration of MetLife's digital platform.
I got lost in screens — there were too many steps, I get lost in more than one or two screens.Participant feedback — Task 7, payment receipt
Most flows tested were found to be generally usable, confirming the strength of the redesign in supporting key tasks.
Task 7 revealed a 36.4% give-up/bounce rate, with users struggling to locate the Payments screen buried in the submenu. This insight highlighted the need for clearer navigation and prioritization of high-frequency tasks.
Participants showed strong comprehension of general terminology, likely influenced by prior familiarity as MetLife and Denizbank employees.
However, 50% of participants confused "Assistant" with "Assistants," pointing to a critical need for simplification and clearer distinction in naming. This became a key recommendation for future iterations.
