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
AVR Maestro is the remote app for Denon and Marantz AV receivers. Control power, volume, inputs and sound modes, then go further: Audyssey, Dirac Live, speaker levels and every zone, from your phone, tablet or computer. It goes past volume and input switching into the settings that shape how your system sounds, through a dark interface built for the home theater. CONTROL AND CALIBRATION Audyssey MultEQ: switch Dynamic EQ, Dynamic Volume, LFC and Containment on the fly. Dirac Live: switch between filter slots to match what you are watching or listening to. Immersive audio: tune IMAX Enhanced crossover settings and Auro-3D processing strength. Speaker levels: adjust every channel, heights and subwoofers included, in real time. THE WHOLE SYSTEM Zones: power, volume and source for Zone 2 and Zone 3 from one dashboard. Remote: a responsive D-pad and transport controls. Scenes and Quick Selects: recall your favourite input, volume and sound mode with one tap. Setup: HDMI settings, 12V triggers, eco modes, front panel dimming and Bluetooth transmitter settings. Now playing: track details and album art for what is playing. PRIVATE AND LOCAL No account and no sign-up. AVR Maestro talks to your receiver directly over your local Wi-Fi, with no cloud service in between. Anonymous crash reports and usage statistics go to Firebase to help fix bugs and improve the app. Fast: native HTTP and Telnet control for near-instant feedback and live volume. COMPATIBILITY Networked Denon and Marantz AV receivers from the last 10+ years that support IP control. The app detects the features your receiver supports when it connects.

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
Expand compatibility to more models, enhancing user base.
Assumption to check: Limited device compatibility with certain models
Validate with people who use this workflow before building.
Hypothesis 2
Implement network discovery for automatic detection.
Assumption to check: Requires manual input of IP address
Validate with people who use this workflow before building.
Hypothesis 3
Add visual or audible feedback for user actions.
Assumption to check: No feedback on command execution
Validate with people who use this workflow before building.
Hypothesis 4
Allow users to customize UI and settings for personal preferences.
Assumption to check: Limited customization options
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.
