Rescue Radar

A time-sensitive marketplace concept for rediscovering canceled food orders nearby.

Independent concept; not affiliated with or endorsed by the product’s owner. Implementation boundaries are described below.

Product flow

  1. 01Nearby rescue offer
  2. 02Review + temporary hold
  3. 03Simulated checkout

The takeaway

Marketplace interaction design only works when operational constraints are explicit.

The product question

Could a canceled, prepared order become a useful nearby offer? The prototype explores discovery, urgency, and framing rather than a real delivery operation.

What I built

A discovery feed, map, ninety-second hold timer, and simulated checkout share offer state. Cached copy supports the demonstration without live language-model calls.

Tradeoffs and boundaries

There is no delivery backend, payment processing, or live inventory. Discounts, activity, and environmental figures belong to the demonstration scenario and are not measured marketplace outcomes.

Before launch, food handling, order eligibility, customer trust, rider rerouting, refunds, and unit economics would need validation. A countdown alone does not establish that a resale window is operationally safe or usable.

Next evaluation

Compare clear savings-led messaging with the sustainability framing. Measure comprehension, offer acceptance, expired holds, and whether customers understand the condition of the order. Retention and waste reduction remain hypotheses.

Prototype outcomes

What this prototype demonstrates

  • A connected offer lifecycle across feed, map, timer, and simulated checkout.
  • A concrete surface for testing urgency and trust.
  • Operational and measurement questions separated from the interaction prototype.
