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
Marriage is a team sport. US! Partner Sync is the to-do app built for two. Instead of drowning in endless task lists, do a brain dump and US! helps each of you pick just three priorities for the day — your Top 3 — plus a handful of Quick Wins. Link your phones once with a simple pair code, and from then on you each see each other's day at a glance.SEE EACH OTHER'S DAY Know what's on your spouse's plate without asking. Watch tasks get checked off in real time, and get a gentle notification when your partner finishes something big. LIGHTEN EACH OTHER'S LOAD See your partner buried today? Offer to pick up one of their tasks with a single tap. Small gestures, remembered. DECIDE THINGS TOGETHER The "Let's Do This Together" list is for shared plans — date night, a Saturday project, an errand for two. One of you suggests it, the other taps "LET'S DO IT!", and it becomes a promise you both can see. STAY FLEXIBLE Life reshuffles your day; the app keeps up. Move any task freely between your Top 3, Quick Wins, and Saved for Later. Brain-dump everything on your mind and let the app suggest a sane plan — then adjust it however you like. CELEBRATE THE WINS Points, streaks, confetti, and little love notes you can send with one tap. Finishing the dishes never felt so appreciated. FOCUS WHEN IT COUNTS A built-in focus timer helps you give your most important task real, undistracted attention. No accounts. No ads. No selling your data. Just the two of you, your priorities, and a simple pair code that links your phones directly. One purchase, a calmer week, and a partner who always knows you're truly both in this together.

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.

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.
