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.

No subscription. On-device transcription is free forever. WristMemo brings your Personal Agent to your wrist: let your AI hear your real day. WEAR IT. FORGET IT. • Keeps recording with the screen off; hold for 1 second to stop, so a stray tap won't end it • Out without your phone? The Watch keeps recording and syncs when your iPhone is back in range • All-day battery (varies by Watch model and settings) NO APPLE WATCH? STILL WORKS • Turn on iPhone-only recording to capture your day with the iPhone mic, even when locked or in another app WHO SAID WHAT, CLEARLY • Free, offline on-device transcription with no time limit, for English, Chinese, Cantonese, Japanese and Korean • Optional cloud transcription with your own API key: Alibaba Cloud, Tencent Cloud or any compatible service, billed by your provider • Alibaba Cloud and Tencent Cloud also label each speaker and recognize your voice AI REMEMBERS WHAT MATTERS • Daily highlights and to-dos, added to Reminders or Calendar in one tap • Ask "What did I promise last week?" Answers cite your exact words; tap to hear them • Turn a meeting into notes or a mind map YOUR PERSONAL AGENT, ON YOUR WRIST • Claude Code and Codex on your Mac can search what you said, the meetings you had and the promises you made • Say it on your Watch, the AI on your Mac gets it done, and the reply comes back to your wrist PRIVACY • No account. Recordings stay on your Apple Watch and iPhone by default • Text or audio goes to the provider you chose only when you use AI or cloud transcription Great for meetings, lectures, doctor visits, interviews, ideas on a run, and voice journaling.

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.
