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.

LastQuake is a free, mobile application dedicated to alerting populations and gathering testimonies in real-time when an earthquake occurs. Designed by seismologists, LastQuake is the official app of the Euro-Mediterranean Seismological Center (EMSC). Thanks to the participative action of its users, only a few minutes are needed for the EMSC to estimate earthquake effects and notify the population. [LastQuake is an ad-free app!] ** AN INNOVATIVE EARTHQUAKE DETECTION METHOD ** EMSC detects earthquakes using: ∘ Earthquake witnesses, who are the first to feel an earthquake, hence the first informed that an event is happening. ∘ Internet and mobile technologies, which allow rapid information collection of the effects observed by witnesses, who are asked to fill in a questionnaire and share photos and videos.

Watch this video: https://www.youtube.com/watch?v=sNCaHFxhZ5E ** COMMITMENT TO POPULATIONS AFFECTED BY EARTHQUAKES ** Information and communication are cornerstones in preventing risky behaviors. EMSC contributes to the reduction of seismic risk by providing you with: ∘ real-time information ∘ post-earthquake safety tips ∘ SMS service that allows victims to notify their loved ones. ** YOUR INVOLVEMENT MATTERS ** LastQuake is a citizen science project. Your contribution helps refine our understanding of earthquake effects while fostering our support in disaster preparation and response. ** KEY FEATURES ** ∘ Real-time information and data ∘ Customizable notifications (destructive earthquakes, earthquakes near you) ∘ Access to comments, photos, and videos by eyewitnesses ∘ Information-sharing via social media ∘ SMS service to notify loved ones when in the area impacted by an earthquake ∘ Post-earthquake safety tips ** WHAT'S NEW ** ∘ Interactive felt map ∘ Customizable notification test ∘ Earthquake notification through voice synthesizer ∘ Copy-paste available for comments ∘ Minor bugs fixed ∘ New languages available: Croatian, Czech, Bosnian, Montenegrin, Hebrew ** WHAT IS EMSC? ** EMSC is an international non-profit scientific NGO founded in 1975. Based in France, EMSC federates data from the seismological observatories of 86 institutes from 57 countries. While operating a real-time earthquake information service, EMSC advocates for public participation in scientific research. Its core product, LastQuake, paves the way for innovative approaches to building more disaster-resilient communities, making EMSC among the pioneers of disaster apps dedicated to earthquakes and tsunamis.

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.
