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

Visual Thinkers Rejoice! Inkflow works like a word-processor for visual thinking. Capture your ideas as easily as with pen and paper, then arrange and reorganize them with your fingers! INKFLOW PLUS This is the full featured Plus Edition of Inkflow. It is the same as the in-app purchase from the basic edition Inkflow. Please download this only if you haven't already upgraded in-App. DIGITAL WRITING DONE RIGHT Inkflow's ink feels like a really smooth fountain pen. Great for expressive writing or sketching. Effortlessly scale or move anything you select. This will change the way you think about ink: Jot down a list of concepts then rearrange them to fit into the bigger picture. literally move your thoughts around the page, and assemble big ideas with your fingers. This works great for brainstorming and planning. It's also perfect for prototyping layouts, sketching, and drawing. FULL RESOLUTION ZOOM Zoom and pan with two fingers. Inkflow's ink stays sharp no matter how much you zoom in, so you can add fine details at full quality. It's also lightning fast and lag free. This allows writing and drawing with incredible precision, with or without a stylus. INKPORT: COPY AND PASTE FROM THE REAL WORLD Only Inkflow Plus includes the revolutionary Inkport tool. Inkport uses your iPad's camera to instantly convert your written notes and sketches into Inkflow's native vector ink. Easily pull in materials from multiple sources and go from paper to iPad without missing a beat. Inkport is going to change the way you use paper in your workflow. TEXT, PHOTOS, and PAPER BACKGROUNDS TOO Insert text boxes and photos anywhere on the page and resize them seamlessly with the ink. You can also choose from a selection of different paper backgrounds.

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.
