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
Welcome to Gene Pool, the app that streamlines the matchmaking process for sperm donors, recipients, and potential co-parents. By leveraging advanced algorithms that factor in DNA markers that influence human attraction and reproduction, Gene Pool brings you closer to finding the perfect match. Beyond genetics, we delve deeper into "personality compatibility," using established psychological types to ensure comprehensive matching. Our platform allows you to connect with like-minded individuals who share your beliefs, hobbies, and passions. How It Works Sign Up & DNA Testing: Register and enter your personality type. If available, submit your DNA testing data. Don't have the data yet? No worries! You can add it to your profile later. Scientific Matchmaking: Complete your Gene Pool profile. Our advanced algorithm predicts compatibility scores based on your DNA markers and personality type. Your Matches: Within ten minutes, you can explore your new matches. Dive into a pool of potential sperm donors, recipients, or co-parents that align with your requirements. Unveiling the Science of Matchmaking Our matchmaking technology is rooted in science. We assess genetic compatibility based on DNA markers that influence human attraction and successful reproduction. Furthermore, we evaluate personality compatibility using the Myers-Briggs 16 personality types. These combined factors allow us to curate an accurate compatibility score, giving you confidence in our matchmaking process. No DNA Test? No Problem! Start your journey with just your personality type and location. Feel free to add DNA tests to your profile at any point. We also offer a free personality test for deeper insight into your compatibility tendencies. Already Have DNA Test Data? You can securely upload your raw autosomal DNA file during sign-up or later while editing your profile. Dive into the Gene Pool today and navigate the waters of genetic matchmaking with confidence and ease!

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.

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.
