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

MemoK is a background voice recorder built for long sessions you can trust. Use scheduled windows or all-day mode, record continuously in the background, and keep files organized with automatic segments. Key features • Background continuous recording Keep recording even when the app is in the background. • Schedule mode + 24-hour mode Run daily time windows or switch to all-day recording. • Smart auto-splitting (1-180 min) Long sessions are saved in manageable segments. • Waveform player Tap any recording to see a live waveform visualization as you listen. • Quick Notes Attach a text annotation to any recording. Notes are bundled with audio when you export. • Custom export filename Add a prefix/suffix or compose a template using variables like {YEAR}, {RANGE}, {LABEL} — only affects exported filenames, never the originals. • Dark / Light / System theme Three display modes to match your environment. • AI dictation is compatible, and Siri dictation no longer interrupts or splits an ongoing recording. • Audio quality options Choose Low / Medium / High based on battery and storage priorities. • Interruption-safe recording Save-first logic with auto-resume attempts after calls or audio conflicts. • Star protection Mark important files so cleanup keeps them first. • Batch export Use Select mode to export multiple recordings (with notes) in one action. • Daily stats + diagnostics export Track effective duration, interruptions, and short segments. Export a lightweight 7-day summary. • Privacy-first Recordings stay on-device by default. No account required. Great for meetings, lectures, interviews, and quick voice memos. Please follow local laws and get consent before recording.

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.
