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

Grafio turns 10. It's been around for a decade already - polished, efficient and with more features than ever before. Grafio is not a tool for professionals only. Its smooth learning curve allows everyone to convey their ideas visually and with ease. Hundreds of thousands use Grafio worldwide, due to its simplicity and affordability. There are no ongoing subscription costs or upgrade charges. Once you purchase it, you have access to an ongoing number of libraries (shapes and symbols) and a multitude of new features with every update. Since Grafio was released 10 years ago, there have been 3 major upgrades, including dozens of new object libraries and a fresh new look to the layout. To begin, simply draw a rectangle, circle or an ellipse and see what makes drawing with Grafio so easy and fun.  Grafio can recognize and replace any of the shapes mentioned with a perfectly looking one for your diagram or schematic, ready to be used over and over. Drag and drop objects on the canvas for more complex diagrams. Make connections, add text labels and images. SHAPE RECOGNITION The shapes you draw are automatically closed and straightened, all basic shapes are instantly recognized. The lines you draw between shapes are automatically turned into connections thanks to our shape recognition magic. STENCILS Some diagrams require more advanced objects. Grafio provides thousands of shapes that you can easily drag in from the library. In addition, you can embed images from your Camera Roll into shapes and connect them to your other shapes. AUDIO RECORDINGS Recording audio notes to your shapes can be a way for you to collect your thoughts and include them in the finishing product, or as a reference. - Video tutorials on Grafio can be found on YouTube: http://bit.ly/grafiovideo +++ FEATURE SET +++ • Shape recognition - recognizes hand drawn basic shapes • Drag & drop shapes from many libraries • Insert, embed, or paste images • Precise drawing with Apple Pencil • Build diagrams and graphs through connections • Label shapes and connections • Select, move, rotate and scale everything (even scribbles) • Change size, color, opacity and other properties of your shapes • Have a favorite font?

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.
