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.

To do this we utilize community driven open data from a number of amazing projects. We use some magik to compress and package it in a format optimized for mobile devices. Pocket Earth then renders its beautiful vector maps on your device using our OpenGL ES based MagikMap technology. To learn more about Pocket Earth or the community driven open data sources that we use, please visit our website. Don’t forget this: 1. Using the GPS features of this app can significantly affect battery life. Only leave GPS enabled when you need to use it. Continued use of GPS running in the background can dramatically decrease battery life. Pocket Earth only uses GPS in the background for route navigation and gps track recording features. 2. This app uses data from the amazing community driven open mapping project called openstreetmap.org! Coverage detail may vary by region, please visit our website to check the map detail for your regions of interest. 3. Does not currently support all asian texts on the map (Chinese, Japanese, etc).

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.
