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

Label-O-Scope is a privacy-first iPhone app that scans packaged-food ingredient labels and checks them against your personal Avoid List. Wrapped in the playful spirit of a pocket-sized CRT scanner from “the future” as imagined in the past, it helps you spot unwanted ingredients in a flash! Results are deterministic using on device OCR and easy to inspect: • NO MATCHES: No ingredient matching your current Avoid List was detected. • AVOID: One or more ingredients match, with the exact ingredient and rule shown. • TAKE ANOTHER LOOK / POSSIBLE AVOID: The label needs your review, so the app avoids giving a false all-clear. BUILD YOUR OWN AVOID LIST Add individual ingredients or start with optional packs for ingredients people commonly choose to avoid. Every rule remains editable. SCAN OR TYPE Use your iPhone camera, or tap and paste an ingredient list when shopping online. SAVE AND RECHECK FOODS Save foods you want to remember. When you change your Avoid List, saved results update against your current rules. PRIVATE BY DESIGN Ingredient recognition, parsing, matching, and optional Apple Intelligence Smart Suggestions run on device. Label-O-Scope requires no account, and has no ads, analytics, or tracking. When available, saved data syncs through your private iCloud account. Label-O-Scope is a personal ingredient-screening tool. It is not medical, allergy, nutrition, or food-safety advice. Always review the original packaging and manufacturer information to be sure.

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.
