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.

FlockHopper is a turn-by-turn navigation app with one extra trick: for every trip, it generates two routes — the fastest, and an alternative that routes around known automated license plate reader (ALPR) camera locations. You pick which one you want. Camera locations are rendered directly on the map, so you can see what you're driving past, not just route around it blindly. Navigation features include turn-by-turn voice guidance with lane hints, full-screen search with categories and points of interest, and background navigation that keeps directions running with the screen off. On the privacy side: no account, no sign-up, no ads, no third-party trackers, no data sales. Your location is used to compute a route and never stored or tied to an identity. Map tiles are self-hosted, so requests don't route through Google. The navigation core is open-source, built on Ferrostar. FlockHopper is built and maintained by one developer with no investors and no subscription. Everything is free. There's an optional Tip Jar if you want to support the project — it unlocks nothing, it's just a tip. Camera data is community-sourced and coverage varies by region — it won't always be complete or current. FlockHopper is a tool for reducing exposure to ALPR networks, not a guarantee. Follow traffic laws and drive safely. FlockHopper is not affiliated with, endorsed by, or sponsored by any commercial surveillance vendor. Camera data is community-sourced and publicly available.

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.
