Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

OVERVIEW How many times have you been drawing a portrait for hours only to realize that the nose or the eye is in the wrong place? You can use Da Vinci Eye to layout artwork before you begin or even check your work as you progress. Having a hard time seeing where lights or darks go? Breakdown images into layers by color value. Then virtually project those layers on top of your image. You can see exactly where to place the darkest darks, mid-tones, and highlights. CAN'T THINK OF WHAT TO DRAW? Check out our inspiration section for user uploaded reference photos. If you have a great pic, you can even upload your own content for other artists to draw. LEARNING HOW TO DRAW? We have lessons using our unique patent-pending learning method. You can also turn ANY photo into a step by step shading drawing lesson. HOW DOES IT WORK? Based on a tool that has been used by artists for centuries, this app is a digital version of a Camera Lucida. You suspend your iPhone or iPad above or in front of your canvas with a stand, tall glass, or other objects easily found around your house. When you look through your phone, you will see both the image and the canvas simultaneously. It's similar in functionality to an art projector or light box, but with the ability to do so much more. You can draw on any surface, zoom in to draw micro details in your drawing, and you don't have to draw in the dark. WILL THIS HELP ME LEARN HOW TO DRAW? Using Da Vinci Eye, you will be training your eye to recognize proportions and draw with shading while training your hand to translate precise lines and strokes on paper. You’ll learn faster and more efficiently using our proven techniques compared to any other app. AR MODE REQUIREMENTS To use AR mode, you must have an A10x or A11 processor and above. We recommend using: – iPhone 8 and newer (iPhone 7 and below will not work) – iPad Mini 5th Generation and newer – iPad Air 2019 and newer – iPad Pro 3rd Gen (Any pro made after 2018) and newer AR & CLASSIC MODE AR mode anchors your image to an object in the real world. This lets you move your canvas or phone, and the drawing and projected image will stay aligned. Classic mode is like a normal art projector, where if you move your phone or canvas, the drawing will no longer be aligned. AR mode is especially useful for drawing or painting on an easel. However, in most cases, Classic mode will achieve the same result. TAKE YOUR DRAWING TO THE NEXT LEVEL Download Da Vinci Eye today! No one ever regretted sharpening their drawing skills.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
