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
Time Progress turns the passage of time into clear, colorful progress rings. See how far you are through the current day, week, month, year, and hour at a glance. Make it yours: • Choose individual ring colors or apply a coordinated color preset • Show only the rings you care about • Reverse percentages to focus on time remaining • Use the built-in focus and break timer • Create custom countdown rings for events • Set optional local milestone and event reminders • Add configurable Home Screen and Lock Screen widgets Widget options include Single Ring, All Rings, Progress Overview, and a circular Lock Screen progress ring. Supported Home Screen sizes range from small through large, plus extra-large on supported iPads. Everything is calculated locally using your device’s system date, time, calendar, and time-zone settings. No account is required, and the core app works without an internet connection. Your settings and custom events stay on your device. Time Progress contains no advertising, analytics, or tracking.

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 animations or notifications for completed tasks.
Assumption to check: Lack of user feedback on task completion.
Validate with people who use this workflow before building.
Hypothesis 2
Allow users to add tags and notes to tasks.
Assumption to check: Limited customization options for tasks.
Validate with people who use this workflow before building.
Hypothesis 3
Integrate with calendar apps for better task management.
Assumption to check: No calendar integration for due dates.
Validate with people who use this workflow before building.
Hypothesis 4
Provide a simpler overview or tutorial for new users.
Assumption to check: High complexity in visualizing multiple life stages.
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.
