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

BookScanner has been rebuilt. Everything you scanned is still here. On first launch BookScanner brings your earlier scan history across by itself — nothing to export, nothing to restore, nothing to tap. The old library file is read and left exactly where it is, so the version you already had is untouched. Books that came over are marked "From your earlier scan history" in History, and the filter sheet will show you just those. You can run the import again from Settings whenever you like. Your ATOS levels, AR quiz numbers, AR points, word counts, interest levels and Lexile measures come across exactly as BookScanner had them. NOTHING TO BUY Lexile measures, DRA, Fountas & Pinnell / Guided Reading Levels and grade equivalents are included for every owner. BookScanner has no in-app purchases and no subscriptions. FIVE READING LEVELS, AND WHERE EACH ONE CAME FROM - AR (Accelerated Reader) / ATOS — looked up, never estimated - Lexile measures — looked up, never estimated - Guided Reading Level (GRL) / F&P — looked up from Scholastic when Scholastic has it; otherwise BookScanner estimates it and marks it ≈ - DRA (Developmental Reading Assessment) — marked ≈ when BookScanner estimates it - Grade level equivalent — marked ≈ when BookScanner estimates it Above P, BookScanner doesn't estimate a Guided Reading Level: where Scholastic has no level for a longer chapter book, BookScanner shows none rather than a letter it can't stand behind. NOW ON MAC BookScanner runs on the Mac as well as on iPhone and iPad, on the same purchase. Scan with the webcam at your desk. Your history is kept in your own private iCloud database and syncs to your other devices. UNITED STATES AND UNITED KINGDOM The ARBookFind region switch is in Settings to choose your region. IMPORT AND EXPORT - Export your library to CSV — sixteen columns, including where each level came from - Import a CSV, including a file exported from the earlier BookScanner - Export to PDF for printing, and share a single book or your whole library HOME SCREEN WIDGETS Recently scanned books and one-tap scanning, right on your Home Screen. Used by teachers since 2012. Rave Reviews: "My kids and I love this app. It's very helpful and convenient."

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.
