I conducted exploratory testing for Sens.ai and identified several issues: inconsistent UI state, missing validation for profile fields, and insufficient feedback, which affect usability, clarity of system behavior, and overall user trust. Comprehensive usability and functional testing should help resolve these issues and ensure the app delivers a smooth and enjoyable user experience.
