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.

Colorlogix makes it easy to design palettes, adjust, convert, and share colors. Powerful controls let you quickly switch between color models, component formats, and color spaces. Share your colors to images, CSS, Swift, SwiftUI, and more. Upgrade to Colorlogix Pro to unlock the full feature set including color combinations, sharing to source code, image color picking, live camera color picking, customizable color lists, and iCloud Sync. • Edit Colors Colorlogix handles color model conversions and formats for you. Just one tap converts between RGB, HSB, HSL, or CMYK. Edit values as integer, hex, percent, decimal, or degrees. A custom hex keyboard makes editing hex values simple. The interactive color wheel and slider controls react simultaneously as you adjust colors. Choose between Red-Green-Blue or Red-Yellow-Blue color wheels. • Create Color Combinations (Pro) Easily create Complementary, Split Complementary, Triad, and Analogous color combinations. Related colors are automatically linked together and updated as you make changes. Adjust the offset angle of Analogous and Split Complementary color combinations. • Pick Colors Pick colors from images or with a live camera view (Pro). The Colorlogix color picker provides a precise, zoomable interface for finding colors. View both RGB and HSB values as you pan within the image. A convenient popover color picker lets you quickly pick from a color grid or from lists of common colors. Choose from CSS Colors, iOS System Colors, Grayscale, and more. Customize the popover color picker to include your own custom color lists (Pro). Custom color lists are automatically synchronized between devices with iCloud Sync. • Design and Share Palettes Create your own library of color palettes with Colorlogix. Synchronization with iCloud (Pro) lets you access palettes on all your devices. Each palette can be rendered in sRGB or Display P3 color spaces, and you can easily convert between color spaces. Share your palettes as reference card images, hex, or source code (Pro), including CSS, Swift, and SwiftUI. • Share to Source Code (Pro) Colorlogix makes it easy to share your colors to CSS, Swift, SwiftUI, or Objective-C. With syntax-colored source previews you can easily view and adjust the code. Using Universal Clipboard on iOS or iPadOS makes it easy to copy a color from Colorlogix to your Mac.

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.
