What the app does

Free Crumbs is a mock mobile-style app that shows nearby free baked goods within 1 mile. Each listing shows the food name, a priority level (critical / high / medium), the source channel (Nextdoor, Office Slack, bakery alert), how far away it is, pickup instructions, allergen tags, and a mock "Claim" button. The bottom tab bar has five sections: Feed, Map, Sources, Log, and Stats.

Observed behavior

• The Feed tab shows three mock listings with realistic detail — timestamps, poster notes, exact pickup directions, and distance.
• Priority badges use a color-coded system: "critical" (croissants running out fast), "high" (banana bread), "medium" (leftover cake).
• Allergen tags are shown inline on each card — nut_free, contains_nuts, contains_gluten, etc.
• The bottom nav suggests other views exist (Map, Sources, Log, Stats) but all are likely placeholder tabs with no content.
• The "Claim (mock)" button is present but does nothing — it's a UI demo only.

Things that didn't work as expected

• The timestamps use Chinese date format (2月25日) even though the app targets an English-speaking audience. This looks like a locale leak from the developer's system, not an intentional design choice.
• "Claim (mock)" is labeled honestly but gives no feedback at all — not even a toast or a disabled state after clicking. A claimed item should visually change.
• There is no allergen filter. A user with a nut allergy has to read every card manually — the tags are there but not actionable.
• Distance is shown (0.2 mi, 0.6 mi, 0.4 mi) but there is no sort-by-distance option or any way to reorder listings.

Suggested improvement prompt

Improve the Free Crumbs mock app with the following changes:

1. Allergen filter bar — add a horizontal pill filter above the feed (e.g., "nut-free", "gluten-free", "dairy-free") that hides cards not matching the user's filter. This makes the allergen tags actually useful.

2. Claim interaction — when the user clicks "Claim", change the button to "Claimed ✓", gray it out, and add a subtle "reserved by you" badge to the card. Optionally show a toast: "Pickup confirmed — head there within 20 min."

3. Locale fix — use the browser's locale (navigator.language) or default to English date formatting so timestamps don't appear in Chinese on English-locale devices.

4. Sort and filter controls — add a small sort dropdown (by distance, by recency, by priority) so users can prioritize what matters most to them.

5. Stub out the other tabs — even a simple placeholder with one or two mock data points for Map, Log, and Stats would make the app feel more complete and demonstrate the full product vision.
