Generating… usually about a minute.
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.

Quirky US Explorer offers a unique take on a travel app. Of course, it will allow you to track where you've been and where you want to go. But it will also let you look at unique locations in those areas. The locations included have been hand-selected by me - not using AI. This offers my unique take on exploring the US and its many quirky locations. So you'll get a chance to delve into my mind and see the things that I find interesting across the US. I will do my best to not scare you away. All of them come with an image and description (usually lighthearted and a bit silly) so you know what to expect. The app uses the native Apple Maps in order to keep the experience easy to use and familiar, while still adding little twists and fun tweaks. Selecting a state will bring up a scratch-off card before you can see the details in the state. But there is also a list of states that allows you to drag them into the categories they fit into - whether you have visited them, or want to visit them in the future. Then you get to the locations. They are organized by states - either all states, or just the states you've already scratched off. They are also searchable in order to make finding places quick and easy. The locations included contain a variety of sites all across the country. There are museums, parks, statues, art installations, natural structures, historical sites, and many other quirky locations that defy description. Some sample sites that are already included: - Whale Bone Arch in Alaska - Rita the Rock Planter in Colorado - Planet Word in Washington, DC - Idaho Potato Museum in ummm... yeah, Idaho - Biggest Ball of Twine in Minnesota which is strangely located in Minnesota - Mothman Museum in West Virginia

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.
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.

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.
