Family UX

Priority: P1 (HIGH)

Declare First

• Surfaces: parent, child, or both. Age band (for example 3-6). Locale. Devices: phone and tablet.
• Content, milestones, and examples must match the age band.

Score Six Axes (0-3, cite evidence)

1. Audience fit: parent and child surfaces separated; parent gate before settings, purchases, external links, and deletion.
2. Accessibility: text contrast 4.5:1 (3:1 large); body 16px, labels 14px minimum; targets 48px parent, 64px child; icon buttons have accessible names; status never colour-only; reduced motion respected.
3. Safety and trust: AI output labelled and separated from clinician-recorded data; no "verified" badge without a source; destructive actions two-step with export or restore; no dark patterns. Store and COPPA rules: mark needs validation, never assert compliance.
4. Comfort: calm palette, one accent; no countdown timers, streak guilt, or red badges for non-urgent items.
5. Consistency: one design system; identical navigation on every top-level screen; one language per screen; locale dates; primary action in the thumb zone; tablet uses two-pane or a rail, not a stretched phone.
6. Human feel: sample people agree across screens (names, ages, dates); one illustration style; no empty placeholders, filler hints, AI cliches, or invented metrics.

Criteria: Rubric. Child rules: Child surface. AI tells: Human feel.

Findings

• Severity: Blocker (audience fit, safety, or AA contrast on a primary action), Major, Minor, Human-feel.
• Row: severity | axis | screen | evidence | consequence | smallest fix | edit prompt.
• Cross-screen check: allergies, conditions, names, ages, and dates agree everywhere. Contradictory medical data is a Blocker.

Anti-Patterns

• No bold for its own sake: maximalist, dramatic, or perpetual-motion styles tire parents and distract children.
• No urgency mechanics: countdown timers, streaks, and loss framing on child surfaces.
• No colour-only status: pair colour with an icon and a word.
