What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

The original AdBlock - the first and last ad-blocker you'll ever need. A one time purchase - no subscriptions needed. We've been blocking ads on iPhones and iPads since 2012 - we know our game! :) AdBlock allows you to block ads on your iOS device. Get rid of 99% of annoying popups, banners and video ads. Protect your privacy, limit bandwidth use, speed up your device, save battery and drastically improve your day-to-day iOS experience. The most important advantages of AdBlock are: • AdBlock comes with a local DNS proxy service built-in. Use it to see which domains you're device is contacting. Create your own rules and assign any IP to any domain, right on your device. You can (and should!) bootstrap this feature with rules found online. • AdBlock has enhanced DNS proxy rules export and import function. Share DNS proxy rules with other users, easily import rules found on the Internet. • AdBlock comes with a Safari Content Blocker to block ads on websites in Safari. • AdBlock allows you to create your own list of domains and synchronize your rules between all your devices using iCloud. • AdBlock allows you to protect your privacy by blocking mobile trackers. Prevent Internet trackers from recording your online activity and selling your private data. • AdBlock does not send your Internet traffic through any remote server. All of your connections stay direct, fast and secure. Ads are blocked right on your device! • Setting up AdBlock is simple! Just download the app, and follow the tutorial to set everything up. When in doubt - contact our support! • AdBlock automatically updates to the latest version of the filters on every app run. We keep the ad servers database up-to-date for you. • AdBlock works with Wi-Fi and cellular networks. You don't need to set it up separately for every network you use. • AdBlock comes with a handy widget to quickly change the DNS proxy status when needed. Looking for support? Contact our dedicated support line directly from the app - we'll help you out with the proper setup and answer all the questions you might have.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
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.
