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
XanWeek is the all-in-one childcare scheduling and tracking app built for families with au pairs, nannies, or babysitters. WEEKLY SCHEDULING Plan and manage your caregiver's work schedule week by week. See total hours at a glance, set shifts, request days off, and track weekly hour limits. Navigate between weeks effortlessly with a clean three-week dashboard. SHAREABLE CAREGIVER LINKS Generate a secure link your au pair or nanny can use to view the week's schedule, house info, and care instructions -- no login required. Share a full week or just a single day. Sensitive info like WiFi passwords and door codes are protected behind a slide-to-reveal interaction. CHILDCARE TRACKING Log daily mood, energy, and feeding for each child with fun custom emojis. Track nap times, feeding schedules, bedtimes, and allergies in detailed child profiles. See a rolling 7-day "vibe" overview on the home dashboard. CUSTOM EMOJI GENERATION Upload a photo of your child and our AI generates personalized emoji sets in multiple artistic styles -- watercolor, 3D cartoon, chibi, and more. Pick your favorite or choose from built-in generic sets. FAMILY COLLABORATION Invite your partner, grandparents, or caregivers to the app. Family members get full access while guests get a read-only view. Everyone stays in sync. HOUSE INFO & CARE NOTES Store WiFi passwords, door codes, alarm codes, and care notes in one secure place. Everything your caregiver needs is just a tap away. MONTHLY CALENDAR View your full scheduling history in a monthly calendar with shift hours, day-off indicators, and daily log status at a glance. Built with love for families who want to stay organized without the overhead. XanWeek is simple, fast, and designed to work the way real families do.

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.

BUILD KIT DIFFICULTY
Intermediate
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.
