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
I'll be as clear as possible and start with the reasons NOT to download the app: * If you want to screen mirror paid streaming services like Netflix, Amazon Prime Video, Disney+, etc., do NOT buy the app — no mirroring app will work for that. These streaming services intentionally block screen mirroring using a technology called DRM. * If you want to mirror your screen to devices outside your Wi-Fi network, do NOT buy the app — it only supports screen mirroring within your local Wi-Fi network. This keeps the video stream private and secure within your home network. That’s by design. Now, reasons to buy the app: + EASY & SIMPLE TO USE. I’m a tech-savvy guy, and my job is to simplify things as much as possible for people. I solve problems and make people happy — and I charge a fair price for it. + GREAT QUALITY & LOW LATENCY. The tech is battle-tested in my other app, VlogMonitor (60+ 5-star reviews in the US). + SOUND. Some other mirroring apps don’t support sound. That’s ridiculous and unacceptable. + GREAT SUPPORT. If you run into a problem I didn’t anticipate, I’ll work on it until you’re satisfied. Just check the 5-star reviews on VlogMonitor — many mention the support. + NO SUBSCRIPTIONS. Period. HOW DOES IT WORK? 1. Open the website tvvv.tv in any browser on your TV (or any device, really) — you’ll see a QR code. 2. Launch the app on your iPhone (or iPad) and scan the QR code. 3. It just works. If you run into any issues, please contact me. I’m friendly, I promise. Join the Discord channel, message on Reddit, or email me. --- This app is not affiliated with any of the trademarks mentioned above.

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.
