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.

My Baby Heart Sounds is a quick and easy way to use your iPhone to listen, record and share your baby's heart sounds. Not too long ago, we were pregnant mothers too. While our partners enjoyed listening to our babies' sounds by placing their ears on the tummy, we wanted to capture and share these precious audio-memories ourselves. We tried voice memo apps and other sound-recording apps but felt that there was something more we could do to improve the quality of the sound in a simple setup. Fast forward a couple years and here we are! Why should you try this app? - Minimum time to setup. All you need is your iPhone. Simple instructions are provided within the app and we are here to support you all the way. - High quality sound. Using advanced audio signal processing techniques, we deliver a high quality audio experience that allows you to distinguish your baby's heart sounds. For best results use AirPods. - Listen for free and only pay when you want to record and share. - Secure. All recordings are stored on your phone. We do not have any access to your recordings. You decide how you would like to share your recordings. - Track your pregnancy journey. Get weekly insights on pregnancy symptoms, learn how to read ultrasound scans, monitor contractions, and keep track of your baby’s movements with a kick counter. For best results: - Use the app when you are 20-30 weeks or greater pregnant. - Use the app in a quiet room - Remove any phone case/shell/cover (the iPhone needs to touch your skin to be able to pick up the sounds) - Put the phone in Airplane Mode - Start the app and place the iPhone on your tummy to listen for a clear sound. You may need to try a few different spots. Press "Record" to create a recording - Use AirPods My Baby Heart Sounds Disclaimer: - The My Baby Heart Sounds app is NOT a Medical Device or application.

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.
