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
Health.md exports your health data to Markdown, JSON, or CSV — right on your Mac. Your iPhone collects rich health data every day: sleep, activity, heart rate, nutrition, workouts, and more. Health.md brings it all to your Mac and saves it as human-readable files in your Obsidian vault or any folder you choose. HOW IT WORKS Health.md syncs directly from your iPhone over your local network — no cloud, no servers. Your health data stays completely private. 1. Open Health.md on your iPhone and Mac 2. They discover each other automatically over WiFi or Bluetooth 3. Your iPhone sends health data directly to your Mac 4. Mac exports to your Obsidian vault as Markdown files WHAT YOU CAN EXPORT Export 50+ health metrics across sleep, activity, heart, vitals, body, nutrition, mindfulness, mobility, hearing, and workouts. FEATURES • Multiple export formats: Markdown, JSON, CSV, Obsidian Bases • Custom filename templates and folder structure • Scheduled daily or weekly exports • Menu bar widget with one-click export • Launch at Login for automatic background exports • Individual entry tracking for moods, workouts, and vitals • Keyboard shortcuts (⌘E to export, ⌘, for settings) PRIVACY All data stays on your devices. Sync happens peer-to-peer over your local network. No health data ever leaves your network. SETUP CHECKLIST (IPHONE + MAC) 1. Update both apps to the latest version. 2. On iPhone: Health.md → Settings → Mac Sync → turn on “Sync to Mac”. 3. On iPhone: Settings → Privacy & Security → Local Network → Health.md = ON. 4. On Mac: install Health.md to /Applications, open Health.md, go to Sync, click Refresh. 5. On Mac: when prompted, click “Allow” for Local Network. 6. Confirm: System Settings → Privacy & Security → Local Network → Health.md = ON. QUICK CHECK IF DEVICES DON’T CONNECT • Make sure iPhone and Mac are on the same local network. • Keep Health.md open on iPhone during initial connection. • Turn off VPN temporarily. • Avoid guest Wi-Fi networks that isolate devices. FAQ Q: Why does AirDrop work, but Health.md doesn’t connect? A: AirDrop can use a different peer-to-peer path. Health.md sync requires Local Network permission + Multipeer discovery. Q: Why don’t I see Health.md in Mac Local Network settings? A: The toggle appears after Health.md requests local network access. Open Health.md from /Applications, go to Sync, click Refresh, then allow the prompt. Q: I clicked “Don’t Allow” before. How do I fix it? A: Re-enable Local Network access in system settings, or reinstall the latest app and reopen Sync to trigger the permission prompt again.

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.
