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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Take control of your skin health with Mole Checker: the smartest way to track, monitor, and understand every mole on your body. Your skin changes over time, and catching those changes early matters. Mole Checker gives you the tools to stay on top of it — no medical degree required. WHAT YOU GET: • AI-Powered Skin Analysis — Snap a photo and get an instant assessment using the ABCDE framework (Asymmetry, Border, Color, Diameter, Evolution). Our technology evaluates each mole across clinical criteria so you know what to watch. • Full-Body Mole Map — Pin every mole to an interactive body map. See your entire skin profile at a glance and never lose track of a spot. • Photo Comparison Over Time — Track how each mole changes with side-by-side photo history. Visual evolution is the single most important factor in early detection. • Smart Reminders — Set check-up schedules so you never forget a monthly skin review. Consistency is key. • PDF Health Reports — Export a professional summary of your moles and their assessments to share with your dermatologist. • Privacy First — Your photos and health data stay on your device, secured with iCloud sync only when you choose. Mole Checker is not a diagnostic tool and does not replace professional medical advice. Always consult a dermatologist for concerns about your skin. Start your free trial today and see your skin in a whole new way. --- Mole Checker offers auto-renewable subscriptions for premium access.

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.
