Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
SayRay puts the words on the screen while people talk. Tap Record and the words show up as they are said, in big bold type. Tap to make them bigger. Scroll back to read what you missed. Tap Stop and it is saved. I made SayRay for my friend Chuck. When he started living with dementia, he loved watching the words show up on the screen as we talked. He could scroll back and remember what was said. That is still what this app is for: seeing the words while people talk, for anyone who needs them. PRIVATE BY DESIGN • Your iPhone turns the talking into words. The sound never leaves it. • On iPhones with Apple Intelligence, a tidied-up copy of the words appears next to the original. You always keep the original. • Your saved notes go to your other iPhones through your own iCloud. No server, no account, no tracking. MADE TO LAST • Play a note back and watch each word light up as it is spoken. • Copy or share any note. • Works with no internet after a one-time download. • Light or dark, and text as big as your iPhone can make it. BUY IT ONCE SayRay is a one-time purchase. No subscription, nothing else to buy. I want it to earn its place on your phone for years. ABOUT ME I'm Ray Fernando, an engineer building on my own now. I build live and share the whole journey as I go. I care about the details, and SayRay is built to show it. If SayRay helps you or someone you love, a review and your story would mean a lot to me.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
