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.

Assumption to check: Lack of user reviews indicating trust issues

Validate with people who use this workflow before building.

Hypothesis 2

Include more advanced editing tools like layer support and AI enhancements.

Assumption to check: Limited editing features compared to competitors

Validate with people who use this workflow before building.

Hypothesis 3

Provide a clear value proposition for in-app purchases.

Assumption to check: Unclear monetization strategy

Validate with people who use this workflow before building.

Hypothesis 4

Implement cloud storage options for user prints.

Assumption to check: No cloud backup for saved prints

Validate with people who use this workflow before building.

App Store description

Dottre turns photos into CMYK halftone prints. Split images into Cyan, Magenta, Yellow and Black. Adjust dots, density and registration. Experiment with paper stocks, and use Portrait depth to separate subjects from their backgrounds before printing. Built for photographers, designers and printmakers. WORK IN DOTS, NOT PIXELS Every image is rebuilt from halftone dots. * Control dot size and density. * Create clean screens or heavy print textures. * Shape contrast through the printing process. THINK IN PLATES Build the image one plate at a time. * View or isolate CMYK channels. * Print in colour, mono or negative. * Decide how each plate contributes. PERFECT IS OPTIONAL Real print is rarely perfect. * Offset channels. * Introduce registration drift. * Create subtle movement or bold separation. BRING THE SUBJECT FORWARD Portrait photos can use depth information to separate subjects from the background. * Isolate people naturally. * Print onto coloured or textured paper. * Create bold poster-style compositions. CHOOSE YOUR SURFACE Print onto more than white paper. * Newsprint * Kraft * Matte * Fine Art * Custom colours MADE FOR PRINT Create posters, zines, artwork and experimental graphics. Because sometimes the print is more interesting than the photograph.

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.
