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
EasyScan QR helps you scan QR codes, create QR codes, and recognize text in one easy-to-use app. Scan QR codes instantly with your camera, or import an image from your photo library. Once a code is scanned, you can review the result and choose what to do next: open, copy, share, or save. You can create QR codes for many everyday needs, including text, website links, Wi-Fi access, email, phone calls, SMS messages, contact cards and locations. EasyScan QR also includes OCR text recognition. Capture text with your camera, review the extracted result, and share it whenever it is useful. All recent scans and created codes are stored in History, so previous results are easy to find. Whether you are sharing a link, connecting to Wi-Fi, saving contact information, or extracting text from a document, EasyScan QR keeps the process simple and clear.

Opportunities
AI-GENERATED OPPORTUNITY HYPOTHESES
These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.
Hypothesis 1
Implement enhanced scanning algorithms to improve accuracy.
Assumption to check: Users often report issues with QR codes not scanning correctly.
Validate with people who use this workflow before building.
Hypothesis 2
Include a comprehensive history section that saves all scanned QR codes with timestamps.
Assumption to check: Many apps in this category lack a history feature, making it hard to track past scans.
Validate with people who use this workflow before building.
Hypothesis 3
Allow users to customize how results are displayed and shared.
Assumption to check: Limited customization options for scan results.
Validate with people who use this workflow before building.
Hypothesis 4
Keep the app ad-free to enhance user experience.
Assumption to check: Some QR scanning apps have intrusive ads.
Validate with people who use this workflow before building.
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.

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.
