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
Make gentle air punches count on Apple Watch. JabPop estimates four punch shapes for your wearing wrist and turns movements into sounds, haptic feedback and combos in a guided one-minute break. ESTIMATED PUNCH SHAPES, NO PERSONAL CALIBRATION Choose your wearing wrist in Settings, then play. On-device recognition automatically estimates straight, hook, uppercut and diagonal shovel-hook shapes for the hand wearing your Watch. No personal calibration or training groups are required. Ambiguous movements can remain unknown. Shapes are approximate and do not measure target height or technique. FOUR IMPACT SOUNDS Choose Classic bag, Heavy impact, Crisp punch or Comic spring. Tap a sound to preview and use it; tap it again to replay. Classic bag is the default; your choice stays on your Watch. Comic spring combines an impact with a short spring effect. START A ROUND Wear your Watch securely, choose your wearing wrist in Settings, and tap Start a round. Read the guide, then begin a one-minute movement break: relax your shoulders, make small gentle air punches at your own pace, and ease off before it ends automatically. There is no punch target. Stop whenever you need. Review your count and best combo afterward. LOOK BACK Check today's count and your best combo. Browse up to 1,000 recent movement records stored locally on your Watch. MADE FOR APPLE WATCH Use JabPop directly on your Watch without an iPhone companion app, account, ads, subscriptions or in-app purchases. Motion is processed on your Watch. Records and preferences stay locally on the device; the app does not send them to the developer. Only the wrist wearing your Watch is detected. Counts are approximate, not coaching or measurements of technique, force or fitness. Keep movements gentle, leave space around you and stop if uncomfortable.

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.
