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
Send every Apple Health metric you choose to any webhook automatically. HealthRelay reads the HealthKit data types you enable and delivers them as JSON to any URL you configure: n8n, Zapier, Make, Home Assistant, a Notion or Airtable automation, or your own backend. No middleman servers, no account required your data goes straight from your device to the URL you own. **WHY HEALTHRELAY** **SEND TO ANY WEBHOOK** Configure as many webhook endpoints as you need, each with its own HTTP method, custom headers for auth tokens, and a choice of batched or one-request-per-sample payloads. **TRACK 20+ METRICS** Steps, sleep stages, heart rate and HRV, blood oxygen, blood pressure, glucose, weight, workouts, nutrition, mindful minutes, and more. Toggle each one independently nothing is read unless you enable it. **RUN MULTIPLE WEBHOOKS AT ONCE** Send different metrics to different destinations. Steps to Home Assistant, sleep to Notion, everything to your own dashboard — all from one sync. **AUTOMATE RELIABLE DAILY SYNCS** iOS limits background app refresh, so HealthRelay ships a Shortcuts automation action. Add "Sync Health Data" to a Personal Automation — every morning at 8am, for example — for dependable, scheduled delivery. **RETRY FAILED DELIVERIES IN ONE TAP** Every attempt is logged with full request and response detail, HTTP status, and duration. A failed webhook doesn't mean lost data — retry it with a single tap. **BUILT FOR PEOPLE WHO SELF-HOST AND AUTOMATE** If you run n8n, Home Assistant, or your own scripts and want your health data flowing into them the same way everything else in your stack does, HealthRelay is built for exactly that. **PRIVACY, BY DESIGN** HealthRelay has no backend. Your data goes from your device directly to the URL you configure — never through our servers, because we don't have any. Read access is granted per data type, and you can revoke it anytime in Settings.

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.

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.
