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

Here’s what quilters tell us — “I really like this app. Just used it to get cutting layouts for a purchased pattern—wasn’t sure I’d been given enough fabric…” “Love this app. I use the calculator portion all the time for back size and cutting dimensions and also binding.” “This is easy to use and the QuiltSandwich Team is quick with replies and help should you need it…” More QuiltSandwich features: Download a free pattern from the web site, then edit the fabrics and piece sizes to fit your project. Design your own Pixel Quilt from a favorite image! Begin with the app Color Hints Mosaic to transform your image into a mosaic as realistic or abstract as you chose. Next, share to QuiltSandwich, setting the size of the pieces (the mosaic tiles) to get a quilt top at the size you want. That’s it! QuiltSandwich has three main tools and a handful of utilities:   QUILT PLANNER organizes a project’s pieces and fabrics into an at-a-glance summary. Plus — Color Mix helps you check the color balance by showing you the mix of colors in proportion to each other. Journal captures your quilt projects so you keep the quilt’s story and pictures after giving the quilt away. AirDrop lets you share your patterns to another iPhone or iPad with QuiltSandwich.   YARDAGE CALCULATOR figures yardage using finished sizes and creates a cutting diagram that shows how to fold and cut the fabric and get all the pieces. Plus — Includes sashing, borders, batting, backing and binding. Just a tap adjusts the cutting diagram for one way design fabrics. Allowance adjustments for seam, shrinkage and squaring-up.   FABRIC STASH keeps images of project fabric organized with the project. You can even add fabrics before assigning them to a project.   NOTIONS is filled with helpful utilities — Shopping List for pieces that don’t yet have a fabric or whose yardage is ‘short’. Fabric List PDF with all the fabrics in a quilt project, noting pieces that do not yet have a fabric assigned. Pattern PDFs is the full set of quilt documents — Cutting Diagrams, Fabric List and Journal — to Share by email, view in iBooks, or print. Triangle Calculators are unique! They calculate dimensions for corner, setting, and right triangles. Size it! finds the percentage needed to enlarge or reduce a quilting design or appliqué pattern using current and desired sizes. Pixel Quilt How-to Guide. Reference Tables with mattress sizes, common batting sizes, and conversion tables. Links to How-to guides. Manager for images saved in the app.   We wish you happy quilting with QuiltSandwich!

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.
