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.

Audiogram Maker is a small utility that does one thing: it lets you copy threshold values from a paper audiogram — the printed test results from your audiologist — into Apple Health. Once your audiogram is in Apple Health as a standard HealthKit audiogram sample, iOS features that read it can use the data. AirPods Hearing Assistance, Headphone Accommodations, and Personalized Volume all consume this data directly from Apple Health. THIS APP IS NOT A HEARING TEST. It does not generate, calculate, estimate, or measure threshold values. Every value is one you type in by hand from a test administered by a qualified hearing healthcare professional. THIS APP IS NOT A MEDICAL DEVICE. It does not diagnose, treat, cure, or prevent any condition, and it does not provide medical advice. It is not affiliated with, endorsed by, or partnered with any hospital, clinic, audiology practice, university, government agency, or other health organization. WHAT YOU CAN DO • Enter threshold values for both ears at the standard audiometric frequencies (125 Hz through 8 kHz, including the interoctaves) • See a live audiogram chart as you enter values • Save to Apple Health as a standard HKAudiogramSample • Browse past audiograms in History • Re-edit a previous audiogram by duplicating it as a new draft • Optionally label each sample with the clinician's name, the clinic, and free-form notes PRIVACY • All processing happens on this device. The app makes no network requests beyond what Apple's system services require for app installation, code signing, and HealthKit's own operation. • The app collects no analytics, identifiers, telemetry, advertising data, or third-party tracking. • Audiogram data is written to and read from Apple Health using only the permissions you grant. The app stores no separate copies of your data outside of Apple Health. • Free-form fields you optionally enter live in the HealthKit sample's metadata on this device. • Your Apple Health data is owned and controlled by you. Apple Health enforces its own privacy and access policies — refer to Apple's Health privacy documentation for details. • Deleting an audiogram in this app removes it from Apple Health permanently and cannot be undone. ALWAYS rely on your audiologist's interpretation of your test results. If you have any concerns about your hearing, consult a licensed hearing healthcare professional. Do not use the data in this app, or any device feature consuming that data, as a substitute for clinical evaluation or treatment. The accuracy of the data is only as good as your transcription of the paper audiogram.

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.
