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.

Find the right word wherever you go. The official RhymeZone iOS app is a fast, powerful rhyming dictionary and thesaurus that you can use anywhere, even if you're not on the net. Quickly find rhymes, near rhymes (including slant rhymes), synonyms, antonyms, homophones, similar sounding words, words with the same consonant pattern, and other related words (generalizations, specializations, words appearing in the same context). Use Apple's local dictionaries or ours online if you are unsure of any meanings. You get a database of over 150,000 words and phrases right at your fingertips. Find rhymes without an Internet connection, but if you are online, we'll connect you to RhymeZone.com for definitions and all the other great features you've come to love, ad-free! Or you can look it up on our sister site, OneLook.com, or even hear it pronounced with your device's built-in text-to-speech. There's also a nifty "Poet Maker" feature, which lets you find words that match constraints on both rhyme and meaning at the same time. For example, suppose you want a word that rhymes with "cat" and means "heavy"; this feature will answer "fat" in no time. Or suppose you're looking for a rhyme of "curious" that means "invalid"; you'll get "spurious". You get the idea! So whether you're aspiring to be the next Shakespeare, looking to put on the finishing touches of a love poem, bust out the next rap lyric, or just seeking some clever wordplay for your English assignment, give the app a try!

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.
