Act as a senior UX researcher and mobile product designer.

Audit the attached [INSERT LINK OR ATTACHMENT OF MOBILE APP / PROTOTYPE / SCREENSHOTS] for usability issues.

Context:
- Product: [PRODUCT NAME]
- Primary user: [USER PERSONA]
- Main user goal: [PRIMARY TASK TO COMPLETE]
- Business goal: [CONVERSION / ACTIVATION / RETENTION / PURCHASE GOAL]
- Platform: [iOS / ANDROID / MOBILE WEB]

Evaluate the experience for:
- Navigation clarity
- Information hierarchy
- Readability and visual clutter
- Button and tap-target usability
- Forms and input friction
- Onboarding complexity
- Error prevention and recovery
- Accessibility
- Consistency across screens
- Unnecessary steps or cognitive load
- Trust and confidence signals

For every issue, provide:
Screen/Step | Usability Problem | Why It Matters | Severity | Recommended Fix

Prioritize findings by user impact and effort to fix.
Do not suggest redesigns simply for aesthetic reasons. Focus on problems that could meaningfully affect task completion, conversion, or user satisfaction.

Finish with the five highest-priority improvements and explain what should be tested first.
