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

Alt Time puts the times you actually need right on your lock screen. See the opposite of your iPhone's clock format at a glance. If your phone shows 12-hour, the widget shows 24-hour — and the other way round. It follows your system setting automatically, so there is nothing to keep in sync. WHAT YOU GET World clock — a home screen widget in small, medium or large, showing as many cities as you like in eight color finishes, with a sun and moon day-night glance. Looks right in StandBy. Alternate 12h/24h time — always the opposite of your system setting, updated automatically. Second time zone — search about 69,000 cities, not just capitals, and see that city's time labeled with its name. UTC / military time — 24-hour Zulu time for pilots, sailors, and anyone working across zones. Dual-time widget — two times side by side in a single lock screen slot, sized to match. Lock screen and home screen widgets, in circular and rectangular slots, tinted or clean. COMPLETELY OFFLINE The city database is built into the app. Searching it needs no network, so Alt Time works in Airplane Mode, on a plane, or with no signal at all. Nothing is uploaded, because there is nowhere for it to go. NO SUBSCRIPTION One purchase. No subscription, no ads, no account, and no data collected, stored or transmitted — ever. Requires iOS 17 or later.

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.
