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.

ArtRage Vitae is our Premium Natural Painting application for mobile devices! Get creative on your digital canvas with realistic color blending, mixing oil paint, delicate watercolor, and much more! Ever wanted to try painting your masterpiece but were put off by the mess and expense? Now you can! ArtRage Vitae isn't just about color: It knows how much paint you've used so you can mix it and spread it on a textured canvas. It knows how wet your paint is so you can blend it with other paints. It even knows about the roughness of your paper so your pencils can be used for soft shading. It's not just a special effect either - ArtRage Vitae is a live simulation of the properties of real artistic media that lets you get creative with colors and textures using tools you already know how to use! ArtRage Vitae takes full advantage of the Apple Pencil support for pressure & tilt, and 3D touch on your iPhone when available. Join the ArtRage community: Forums: forums.artrage.com Facebook: www.facebook.com/artrage Instagram: www.instagram.com/artrage_paint/ Features: Real world painting tools: Oils, Watercolors, Paint Rollers, Pencils, Crayons and more. Each tool has a range of familiar properties such as how much thinner is applied to the paint, or how soft a pencil tip is. Tools apply texture as well as color, and blend under the brush. Add Layers to your painting and work on individual elements without damaging others. ArtRage supports a wide range of layer effects, layer blend modes, and layer contents can be scaled moved and rotated independently. Import images, converting them to oil paint for mixing and blending or as Reference Images pinned to the canvas as a visual guide. Load photos as Tracing Images which are overlaid on the canvas, and have ArtRage select colors automatically as you paint. The interface has been designed to maximize your creative space without hiding away critical functions such as tool and color selection. As you paint, it gets out of the way so that you don’t have to stop and manually adjust panels. Record your paintings! The ArtRage Script system lets you record strokes while you paint for playback in desktop versions of the product at higher resolution. Share your paintings on Instagram, Facebook, Twitter, Creative Cloud, Dropbox, DeviantArt or any other sharing app on your device. Tools: • Oil Brush, Watercolor, Airbrush, Palette Knife, Paint Roller, Paint Tube, Inking Pen, Pencil, Marker Pen, Chalk, Crayon, Glitter Tube, Gloop Pen, Eraser, Flood Fill, Cloner. • Paint simulation monitors the physical properties of your paints to allow natural blending, smearing, and other real world behavior. • Preset support to save your favorite settings for later use. • Supports the Apple Pencil's Pressure and Tilt properties, and 3D Touch where available to add realism to the simulated paint strokes. Layers: • Unlimited layers with Photoshop standard blend modes, visibility and opacity controls. Scale, rotate, and position layer contents independently.

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.
