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.

Free quick prompt For a smaller starting point
Quick prompt
Good fit for mobile-first iOS and Android prototypes with managed app scaffolding.

Rork plan preview for No JS: map the core Utilities workflow, choose the smallest differentiated feature set, define the data and monetization boundaries, then prototype the riskiest user journey first.

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
Add more web-related checks like SSL or performance metrics.
Assumption to check: Limited functionality beyond checking JavaScript status
Validate with people who use this workflow before building.
Hypothesis 2
Implement iCloud sync for user history.
Assumption to check: No account sync or backup of history
Validate with people who use this workflow before building.
Hypothesis 3
Enhance UI with animations and transitions.
Assumption to check: Less interactive UI
Validate with people who use this workflow before building.
Hypothesis 4
Allow users to save checks and view history offline.
Assumption to check: No offline capabilities
Validate with people who use this workflow before building.

App Store description
Ever find yourself viewing a webpage when something annoyingly pops up, like an ad, or paywall, or a prompt to sign up for a newsletter? Or maybe you notice that even after the content has loaded, something is still using your network connection? Enter no.js, a tool that helps you effortlessly, and temporarily, disable Javascript for the page you're viewing. Easily prevent popups, tracking or analytics services, ads, and some paywalls. No need to go into your Safari settings and disable Javascript, only to immediately return to enable to. No need to strengthen content blockers, only to loosen them up again. Just two taps from any Safari view. ** No.js is NOT a content blocker. It is an extension that works in all apps that allow sending URLs to other apps. This means almost any app that has a way to view webpages, but actual mileage may vary. Also, some pages may appear broken when viewing them without Javascript, but good websites won't :)

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.
