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.

Asset Catalog Creator takes any image & turns it into a complete & ready-to-use app icon. It supports every type of icon you'll ever need for any of Apple's platforms; iOS, iPadOS, watchOS, tvOS, macOS etc. It uses the xcasset catalog format & it's always updated for the very latest devices & software. It doesn't just do app icons. It can make any icon within your app; converting your image into all the required 1x, 2x & 3x formats. If you're using vector-based iconography you can preserve all your vector data during the conversion & output your icons as pdfs, while still having control over the size of the image. It even includes a list of preset sizes for standard interface elements, such as tab bar icons, navbar icons etc. As well as in-app icons, it also supports creating everything you need for Complications, iMessage, & Game Center. As of iOS 15, there are 25 different image sizes required to make an iPhone/iPad app! Asset Catalog Creator is configured with well over 100 image dimension requirements. You’ll never need to look a size up again. Asset Catalog Creator is designed to be quick & easy to use & fit seamlessly into your workflow. All you need to do is drag in an image, point the app to where your project is, pick your icon type & export. The app finds the existing asset catalog(s) & has advanced merging abilities that allow it to append or overwrite based on your choices. If you’ve never used Asset Catalogs in your apps before, now is a great time to start. You’ll find managing & organising your image files much easier & you’ll also benefit from improved performance & reduced app install size, thanks to the smarter way asset catalogs are compiled & archived into binaries.

Both versions have an identical set of features but have different pricing structures to suit your preference. Asset Catalog Creator gives you the ability to make iOS app icons out-of-the-box & you need to unlock the ability to create each additional type of icon via in-app purchases. The in-app purchases are all non-consumable so will be unlocked permanently & can be used across all of your computers. The difference with the Pro version is that every type of icon etc. is unlocked out-of-the-box & there is nothing additional in the app for you to purchase.

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.
