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
Adopting a more practical and differentiated design, ReadQR redefines the experience of QR code scanning and generation. This all-in-one code tool supports batch QR code scanning, conventional QR code scanning, barcode creation, QR code generation and scan record management, while featuring an exclusive URL security detection function. For QR code scanning, ReadQR offers a variety of flexible and convenient recognition methods, including real-time camera scanning, local album import and batch scanning. You can instantly scan physical QR codes via your device camera, import saved images and screenshots for recognition, or identify multiple QR codes in one batch to greatly boost scanning efficiency. URL Security Detection, Protects Your Online Safety Most unknown QR codes are linked to web pages that may contain potential security risks. ReadQR is equipped with an exclusive security detection feature for all scanned links. Once the system detects a web URL embedded in a scanned QR code, it will automatically trigger real-time security checks and intelligently identify risky links. The app issues prominent risk warnings for dangerous links and blocks unsafe access in advance. All link detection processes are completed locally on your device, and no detected links will be uploaded or stored on any third-party servers. Practical Auxiliary Functions, All-in-One QR Code Service ReadQR integrates fully-featured QR code generation and record management functions to deliver comprehensive practicality. It supports customized creation of standard QR codes and traditional barcodes, covering a wide range of content types such as plain text, URLs, WiFi connection data, email addresses, phone numbers, social media accounts and geographic locations, meeting personalized code creation demands for daily and business scenarios. Whether you need single or batch QR code scanning for daily information acquisition, scan record sorting, URL security verification, or customized QR code and barcode creation for social and commercial use, ReadQR delivers reliable, one-stop professional.

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.
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.
