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
Brewwww! is a drink-logging app for people who take their cafe runs seriously. Snap a photo of your coffee, tea, matcha, or any drink you love, you will get a vintage postmark stamp featuring the shop name, date, and city. Every cup becomes a small collectible tied to a real place and moment. Keep the full memory in Momento, your instant-photo collection. Browse each month as a two-column photo wall or swipe through your drinks one by one. Customize the frame color, replay the Live moments, and save finished instant-photo cards directly to Photos. Your calendar turns every logged day into a visual diary featuring the drinks you actually had. Switch between month and week views, review your full haul, track how many shops you visited, and choose your Weekly or Monthly Favorite. As you explore, your map fills with pins from cafes and drink shops around the world. Brewport brings the whole journey together like a real travel passport. Track your total cups, shops, cities, and collected stamps. Unlock hand-drawn milestone stamps, Matcha challenge stamps, and discover special stamps from Brewwww! partner shops. One drink, one place, one memory at a time. Terms of Use: https://deadpan-vicuna-73d.notion.site/Terms-of-Use-343ca473a427804aba06e1afc294b82c?source=copy_link

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 drink selection and partner with more cafes.
Assumption to check: Limited drink options compared to competitors
Validate with people who use this workflow before building.
Hypothesis 2
Optimize image loading and caching.
Assumption to check: Slow loading times for images
Validate with people who use this workflow before building.
Hypothesis 3
Implement guided onboarding for first-time users.
Assumption to check: Difficult navigation for new users
Validate with people who use this workflow before building.
Hypothesis 4
Introduce a loyalty program to retain users.
Assumption to check: No reward or loyalty program
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.

BUILD KIT DIFFICULTY
Intermediate
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.
