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.

Gboard is the keyboard from Google for your iPhone, packed with features to make typing effortless. On top of GIFs, emoji search, and Glide Typing, the power of Google is at your fingertips with Google Search built in. Forget switching from app to app – just search and send, all from one place. GIFs — Search GIFs for the best reaction Emoji Search — Find the perfect emoji, faster Stickers - Create or share stickers to express yourself Glide Typing — Type faster by sliding your finger from letter to letter Search and send anything from Google: • Nearby stores and restaurants • Videos and images • Weather forecasts • News and articles • Sports scores • And anything else you’d search on Google Gboard for iPhone and iPad supports the following languages: • Afrikaans • Arabic • Azerbaijani • Belarusian • Bengali • Bulgarian • Catalan • Croatian • Czech • Danish • Dutch • English • Estonian • Finnish • French • German • Greek • Gujarati • Hausa • Hebrew • Hindi • Hungarian • Icelandic • Indonesian • Italian • Japanese • Khmer • Korean • Latvian • Lithuanian • Macedonian • Malay • Maltese • Marathi • Norwegian • Persian • Polish • Portuguese (Brazil) • Portuguese ( Portugal) • Romanian • Russian • Serbian • Simplified Chinese • Slovak • Slovenian • Spanish • Swahili • Swedish • Tamil • Telugu • Thai • Traditional Chinese (Taiwan) • Traditional Chinese (Hong Kong) • Turkish • Ukrainian • Vietnamese • Welsh • Zulu Privacy We know the things you type on your phone are personal, so we’ve designed Gboard to keep your private information private. What Gboard sends to Google: • Gboard sends your searches to Google’s web servers to give you search results. • Gboard also sends usage statistics to Google to let us know which features are used most often and to help us understand problems if the app crashes. • If you use Gboard’s microphone, voice input will be sent to Google for transcription. What Gboard doesn’t send to Google: • Other than your searches and voice inputs, Gboard doesn't send anything you type to Google, whether it’s a password or chat with a friend. • To help you with spelling and to predict searches you might be interested in, Gboard will store the words you type on your device. This data is not accessible by Google or by any apps, and can be cleared at any time. • If you’ve turned on contacts search in Gboard search settings, this allows Gboard to search the contacts on your device so you can easily share. None of these queries are sent to Google.

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.
