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

* A quick sketch of Galadriel (played by Cate Blanchett) from "The Lord Of The Rings" film series; done using Vermeer's Lens, a 2B pencil and blue ballpoint pen on an A4 printer paper. ◉ Vermeer's Lens is no ordinary drawing app. It is a drawing app that helps you make real sketches on paper. ◉ Vermeer's Lens is an augmented reality drawing app that works like an AR projector. It projects any photo you've selected from your photo library on any paper or sketch books you prefer drawing on. ◉ Vermeer's Lens allows you to trace out the images you want to draw before shading. But it is more than a tracing tool, as it also allows you to capture areas of different tones and highlights - achieving a more lifelike picture.  ◉ Vermeer's Lens is a great tool for portrait drawing. ◉ Vermeer's Lens can also be used in short drawing/sketching practices for beginners. ◉ Vermeer's Lens enables even beginners to make stunning drawings. ◉ Through its precise algorithms, what is traditionally difficult, such as portraits, can now be done without the need of construction lines. ◉ This app works on most phones without using Apple's ARKit which can only run on newer high performance chips. It's a simple effective tool for a simple hobby. *** See "Developer's website" below for a video demo *** A Youtube channel (see "Developer's website") is set up to provide you with examples of Vermeer's Lens in action. Content will be regularly uploaded so long as there are people interested in this app. *** This app works on most phones without using Apple's ARKit which can only run on newer high performance chips. It is simple, reliable and stable. ________________________________________________________ How it works : > a photo is chosen from your photo library and “projected” over the paper to draw on. > This projection is achieved by imaging the paper on the phone screen, and overlaying the translucent photo onto it. > With the phone held in a phone-holder, you can use its screen as a lens, through which you trace out the photo onto the paper. > Phone can be tilted and rotated to the angle most comfortable to you, while Vermeer’s Lens transforms the photo to match the perspective of the paper. > Not just the outlines, even the different subtle tones and contours of a face could be captured, to get that 3-D effect. > Opacity of the overlaying photo could be adjusted to allow close comparison between your drawing and the photo. > The overlaying photo responds to on-screen gesture: you could move, scale and rotate the photo during sketching. > A zoom option allows you to zoom in on your drawing for delicate pencil work. in addition : > A Vermeer’s Lens channel is also created on youtube to provide our users with additional "instructions & tutorials"on the use of this app to create art (videos updated regularly). This is linked directly to the app via the “Demo” button. > You can email us for support/feedback directly via the “Contact Us” button on the main menu of the app. Or leave a message (go to the “about” tab) on our youtube channel (see “Developer’s website” below).

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.
