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
Limits shows your AI coding rate limits at a glance. See session usage, weekly quotas, and reset timers for the providers you connect, all in one place. Connect with secure sign in. Limits never sends your tokens to a server. Your tokens stay on your device in the Keychain, and your usage is cached on device so the widgets can read it. Home Screen and Lock Screen widgets keep your limits visible without opening the app. Live countdowns keep ticking between refreshes, so you always know how much you have left and when it resets. Supported providers: - Codex (ChatGPT) - Claude Code - Cursor - Grok - Antigravity - Grok Bot (via Cursor) Why you will like it: - One dashboard for every limit you care about - Ring and bar gauges that stay readable at a glance - Reset countdowns on your Home Screen and Lock Screen - Private by design, with no account required for Limits itself - No ads, no tracking, and no analytics Limits is an independent app and is not affiliated with, endorsed by, or sponsored by Anthropic, OpenAI, Anysphere, Google, xAI, or any other provider. Provider names are used only to identify the services you choose to connect. Terms of Use: https://www.apple.com/legal/internet-services/itunes/stdeula/ Questions or feedback: [email protected]

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
Provide extensive API support for various AI tools.
Assumption to check: Limited app integration options
Validate with people who use this workflow before building.
Hypothesis 2
Simplify navigation and provide guided tours.
Assumption to check: User interface can be overwhelming
Validate with people who use this workflow before building.
Hypothesis 3
Enhance with more data visualizations and insights.
Assumption to check: Lack of detailed analytics
Validate with people who use this workflow before building.
Hypothesis 4
Implement more reliable usage tracking algorithms.
Assumption to check: Inconsistent performance tracking
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.

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.
