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
Pod2Swim turns your swim into podcast time. Bluetooth doesn't work underwater, so Pod2Swim loads your favourite podcasts straight onto a Shokz OpenSwim — or any headset that mounts as USB storage — ready to play, lap after lap. No phone at the poolside, no streaming, no signal required. HOW IT WORKS • Subscribe to any podcast with the built-in search. • Browse the newest episodes from all your shows in one chronological feed. • Queue what you want for your next swim — Pod2Swim downloads it in the background. • Plug in your headset and export the whole queue in a single tap, in playback order. • Scan the headset any time to see exactly what's loaded. BUILT FOR SWIMMERS • Your audio lives on the headset, so you can leave the phone in the locker. • Adjustable playback speed from 0.75× to 2.5× per podcast, with the pitch preserved — fit more in before the pool closes. • Choose Replace All or Add to End on transfer, so you stay in control of what's on the device. • Episodes land in playback order, so your queue plays exactly as you arranged it. SIMPLE STORAGE • The queue is the single source of truth — add to download, remove to free space. • See total downloaded storage and clear it in one tap. • Optional auto-delete after export keeps things tidy. Pod2Swim works with the OpenSwim, OpenSwim Pro, and other MP3-player headsets that appear as a USB drive in the Files app. You'll need a USB-C or Lightning adapter to connect the headset to your iPhone. Pod2Swim is not affiliated with Shokz. Shokz and OpenSwim are trademarks of their respective owner.

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.

BUILD KIT DIFFICULTY
Intermediate
From the Build Kit assessment.
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.
