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

You are holding her. Both hands are gone. Your phone is charging in another room. Hush lives on your wrist, so the sound is already where you are. Raise your arm, press once, and it plays out of the watch speaker. No phone. No pairing. No putting her down. BUILT FOR 3AM Hush is dark by default, and at night it goes darker still — the whole screen shifts to a dim red that will not wake a sleeping baby or ruin your own night vision. Nothing on screen blinks, spins, or pulses quickly. Nothing buzzes unless you ask it to. Every control is sized for one thumb at a bad angle. One press starts the sound. One press stops it. That is the entire app. EIGHT SOUNDS THAT ACTUALLY WORK Rain on canvas. Box fan. Deep hum. Shhh. Heartbeat. Ocean. Hairdryer. Womb. Named for what they sound like, so you can pick the one that worked last night without thinking about it. THE LOG WRITES ITSELF You never record anything. Starting and stopping is the data. After a couple of weeks Hush can tell you the one number that helps: how long it usually takes. Tonight is twenty-two minutes and counting? Usually about fifteen. You are close. No charts. No streaks. No sleep scores. No comparing tonight to last night. An exhausted parent does not need an app implying they are doing worse than average. ON YOUR WATCH FACE Add the Hush complication and the app is one tap away — no scrolling through a grid of apps one-handed in the dark. It shows which sound is set, and whether something is playing right now, so you can answer "is it still going?" without opening anything. RUNS ON ITS OWN Hush is a standalone watch app. It does not need your iPhone nearby, and there is no phone app to install. Start the sound, drop your wrist, let the screen sleep — it keeps playing. Set it to stop after 15, 30 or 60 minutes, or leave it running until morning. No account. No subscription. No data leaves your watch.

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.
