Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Got water stuck in your Apple Watch speaker? SonicClear uses a precision-tuned 165 Hz sine wave — the resonant frequency of the Apple Watch speaker grill — to physically push water out. Combined with continuous haptic pulses, it's the fastest way to restore crystal-clear sound. HOW IT WORKS • A 165 Hz tone plays at maximum volume, creating strong air displacement inside the speaker chamber • The frequency matches the speaker grill's resonant frequency for maximum vibration amplitude • Haptic pulses add physical vibration to dislodge water trapped in crevices FEATURES • One-tap water ejection — just press START PURGE • Real-time visual feedback with animated resonance rings • Elapsed time tracking to monitor your purge cycle • Built-in "How It Works" guide with step-by-step instructions • Optimized 165 Hz frequency for Apple Watch speakers • Combined acoustic + haptic water removal • Premium, minimal design — no ads, no subscriptions INSTRUCTIONS Hold your watch with the speaker facing down Tap START PURGE Wait 15–30 seconds Gently tap your watch on your palm to shake out remaining water Repeat if needed TIPS • Turn the Digital Crown up to maximize volume before starting • Run multiple purge cycles for stubborn water • Works best immediately after water exposure Designed exclusively for Apple Watch. No iPhone required.

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.
