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

Coin Scanner & Value Checker is a powerful mobile app — your all-in-one AI-powered coin identifier and coin values checker app — for fast, reliable coin value lookups. What it does Snap a photo (both sides) or upload an image — our AI coin scanner matches it against a large catalog to return the coin identification value, current coins prices and values, and key details (mintage, metal, year, mint mark). It’s an easy app to value coins whether you’re sorting finds, doing a quick coin appraisal, or managing a collection. Identification process 1. Select or shoot: Choose from gallery or photograph the coin (obverse & reverse). 2. AI match: The app recognizes type, year, and mint, then estimates coin value. 3. Details & trends: View specifications, rarity notes, and pricing history to evaluate rare coins worth considering. Why collectors love it • Instant recognition: Point, scan, and identify rare coins and common issues alike — see which coins worth money. • Pricing insights: Review up-to-date coin value ranges, including mint coins value and market comps. • Pro tooling: Handy for coin collection valuation and quick checks (a true coin checker / coin value app). Instant Professional Grading Meet Grading—the ultimate tool for assessing coin condition instantly. Just snap a clear photo to receive a precise grade estimate and discover how preservation impacts its market price. It’s the easiest way to understand the exact state of your coins and maximize the value of your entire collection.
