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

ilumen turns your iPhone into a compact film camera. Modern phone photos look "digital": over-sharpened, over-brightened, flattened by HDR. ilumen goes the other way. It captures 48MP RAW and develops every shot itself — sharpening off, AI enhancement off — for photos with the soft, dimensional character of a classic compact film camera. FOUR FILM RECIPES • Positive — punchy contrast, deep shadows, warm color • Negative — lifted blacks, soft highlights, muted warmth • Hi-Contrast B&W — crushed blacks, optional grain • Standard — the pure, natural RAW render A REAL PHOTOGRAPHER'S CAMERA • 28mm-equivalent 3:2 framing with bright framelines • The viewfinder shows your recipe live — what you see is what you get • Two-axis white balance shift (amber–blue / green–magenta), per recipe • Softness control that melts digital crispness like a mist filter • Film grain, per recipe — grainy B&W, clean color, your call • Exposure compensation, tap to focus • Every setting remembered per recipe, like film sims on a real camera SIMPLE ON PURPOSE One screen. No menus, no editing afterwards. Press the shutter and a finished photo lands in your library — 48MP, ready to share. PRIVATE BY DESIGN No account, no network, no data collection. Your photos never leave your phone. Full 48MP capture uses Apple ProRAW, available on iPhone 14 Pro and later. Other iPhones shoot 12MP RAW with the same film development. 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.
