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

The cookbook your family builds together — for the recipes you save, the ones you cook, and the people you cook with. Heirloom is a private place for every recipe that ends up on your family's table. SAVE FROM ANYWHERE A link, a handwritten card, a voice note, a cooking video, or a few words you type yourself — Heirloom turns every way a recipe shows up in your life into a proper recipe card you can cook from. KEEP FILLING THE BOOK Not a file folder. A cookbook. Name it, style it with one of 20 designed templates, and add the recipes that matter to your family in one private place. Every recipe remembers who added it, when, and what they changed from the original. A real cookbook, built the way Grandma kept her binder. SHARE WITH THE PEOPLE YOU COOK WITH Sharing is a deliberate act. Send a private invite link to the people you choose. No public feed. No follower counts. No algorithm. Your cookbook is yours and theirs — no one else's. WHAT'S FREE, WHAT'S PREMIUM Every recipe is private by default. You choose who sees each cookbook. Free, forever: save any recipe from a link, type recipes by hand, build cookbooks, share with the people you cook with, 14-day free trial of Premium. Premium ($6.99/month or $39.99/year): voice notes, cooking-video import, handwritten card scanning, bulk cookbook scanning (500+ page PDFs), AI Spark, unlimited cover art, and all 20 designed templates. BUILT TO KEEP GROWING - On-device voice transcription — your audio stays on your phone - Lineage on every recipe — see whose version this is and where it came from - Free to start — sharing and core features never gate behind a paywall HEIRLOOM IS NOT - Not a recipe discovery app. We don't suggest what to cook tonight. - Not a social feed. Your cookbook is not a follower count. - Not a meal planner. We don't tell you what's for dinner. - Not a public profile. No one finds you by searching. A product of Rationale.

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.
