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.

Fog & Clouds Finder — sunrise scouting for landscape photographers Fog & Clouds Finder is a focused planning tool for photographers who chase moody fog and dramatic sunrise / sunset skies. It is not a general-purpose weather app — it answers two questions: where will there be fog tomorrow morning? and where will high clouds light up at golden hour? What it does • A live map heatmap showing fog likelihood and high-cloud cover across any region, refreshed automatically as you pan and zoom. • Tap any spot to drop a pin and instantly see sunrise & sunset times for that exact location, plus the forecasted fog and high-cloud percentages at those moments. • A 72-hour time slider with golden-hour and blue-hour markers so you can scrub straight to the moments worth shooting. • A country picker with 45+ photography destinations — useful for trip planning. • Compass direction of sunrise and sunset at every spot, so you know which way to face the tripod. • All times shown in the local timezone of the place you're scouting. How it works Forecasts come from Open-Meteo's free, global weather API. Fog likelihood is a heuristic blend of low-cloud cover, humidity, dewpoint spread, and visibility — the classic ingredients of fog formation. Sunrise, sunset, and azimuth are computed on-device using the standard NOAA solar algorithm. A note on forecasts Fog and clouds are notoriously hard to predict, especially beyond 24 hours. Treat the badges as guidance, not certainty — but they're a much better starting point than guessing. No account required. No tracking. No ads. Free and open to use anywhere in the world.

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.
