The audit. I ran a full UX audit of the iOS app, looking for usability issues, navigation friction, and bugs standing between users and a smooth learning session. The work went screen by screen, mapping the whole journey from onboarding through daily practice, to understand not only what was not working but why. Heuristic evaluation was paired with a close read of navigation flow, information hierarchy, and interaction patterns. The output was a detailed report: each friction point flagged and matched with a practical recommendation, ordered so the team could act on it rather than admire it.
