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
MeowLog is a beautiful daily journal for cat parents who want to understand their cat better. DAILY MOOD TRACKING Log your cat's mood each day — playful, sleepy, grumpy, lovey, anxious, or create your own custom moods. See patterns emerge over time. ACTIVITY LOGGING Track what your cat did today: zoomies, cuddles, naps, grooming, eating habits, and more. Add custom activities that match your cat's personality. PHOTO MEMORIES Attach photos to any day's entry. Build a visual diary of your cat's life — the silly moments, the cozy naps, the chaos. CALENDAR HEATMAP See your cat's mood history at a glance with a color-coded calendar. Spot patterns you'd never notice otherwise. TIMELINE VIEW Scroll through your cat's story chronologically. Every mood, activity, photo, and note in one beautiful feed. VET REPORTS Export professional PDF reports for your veterinarian. Choose date ranges, include or exclude photos. Share patterns that help your vet understand your cat's behavior. MULTI-CAT SUPPORT Track multiple cats with individual profiles, colors, and themes. Switch between cats instantly. PRIVACY FIRST All data stays on your device. No accounts, no cloud, no tracking. Your cat's diary is yours alone. The journal your vet wishes you kept.

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.
