A product spec, screen plans, and build steps for your coding agent.

Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Falling Fruit is a 501(c)3 nonprofit based in Boulder, Colorado, USA. All proceeds from sales of the app help pay to keep our servers online. We greatly appreciate your support in keeping the project online! Our global map of edibles is not the first of its kind, but it aspires to be the world's most comprehensive. While our users contribute locations of their own, we comb the internet for pre-existing knowledge, seeking to unite the efforts of foragers, foresters, and freegans everywhere. The imported datasets range from small neighborhood foraging maps to vast professionally-compiled tree inventories. This amounts to thousands of different types of edibles (most, but not all, plant species) across thousands of cities around the world. Beyond the cultivated and commonplace to the exotic flavors of foreign plants and long-forgotten native plants, foraging in your neighborhood is a journey through time and across cultures. Falling Fruit is not associated with Fallen Fruit. Fallen Fruit can be found at fallenfruit.org.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
