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.

«ABSTRACTION IS REAL» (J. Albers, 1966) GeometriCam uses the iPhone camera as a live video source to generate stylish geometric compositions in real-time. Explore your surroundings through the eyes of geometry and be amazed by shapes and colors that change as you move around: creating abstract masterpieces has never been so fun and easy! «The fizzing real-time patterns on GeometriCam are reminiscent of those closed-eye hallucinations you get with eyes shut in a darkened room or staring with lids closed at bright lights.» (Kevin Holmes - The Creators Project/VICE) «Whether you use it for an eye-catching selfie or something more unusual, do it soon because GeometriCam offers a look that could well catch on quickly.» (Martin Bryant - The Next Web) With GeometriCam you can: - capture beautifully crisp images and video clips while controlling a powerful GPU-accelerated filtering engine; - import and process images and video clips straight from your photo albums and export professional-quality content; - take total control of different stages of non-linear, non-destructive granular editing through innovative and intuitive tools. LAYOUT Behind the scenes your composition is a grid: use your fingers to change the size and aspect ratio of the cells or benefit from smart tools specifically created to help you adjust, refine and frame the layout. See complex patterns come true in seconds thanks to a special UI designed to offer a streamlined, one-handed experience. SHAPES Enjoy a large variety of shapes to choose from (triangles, squares, diamonds, circles and lines) and see your design moving in a few taps from swiss concrete art to tetris-like scenes, from classic polka dots to pop illustrations. Specify the properties of the pattern units underlying the composition by means of innovative custom controls and experiment with shapes like never before! COLORS Define the color palette of your artwork and lose yourself in the interplay of shapes and colors. Generate standard or monochromatic color filters with a single tap or precisely adjust Red, Green and Blue channels. Modulate the intensity of the filter in order to find the dress that perfectly suits the character of your composition. TUNING Fine-tune the appearance or simply add a finishing touch to your masterpiece. Reduce the color depth to redefine the style of your design (ideal for retro-game or glitchy looks) or apply standard adjustments such as exposure, brightness, contrast, saturation, vibrance and fade. PRESETS Use carefully crafted presets, shipping with the app to get you started, or create your own so you can save and recall your best achievements. Remix and merge existing presets by simply choosing one of the countless combinations of their elemental properties (shapes, colors and tuning): more presets is more fun - just roll the dice and enjoy the surprise! VORTEX Have fun transforming your creations into sparkling circular compositions with this mesmerizing effect. Easily zoom in/out or adjust direction, rotation, swirl and joint angle, all in real-time, all using just your fingers. POLYGON (new in v1.2) Give your creations a dose of magic and get even more kaleidoscopic results with this powerful new effect. Use your fingers to adjust rotation, sampling (the repeating section), slicing (the number of sides) or just zoom in/out. Jump into a world of ever-changing dreamscapes and you’ll never want to go back! — Highlights: - For images and video clips - Real-time preview and processing - High quality output (for printing and further video editing) - Large variety of scalable, stretchable shapes - Wide range of styles, from subtle graphics to abstract scenes - Lots of presets to get started - Fun and easy, encourages experimentation - Designed to offer a smooth, one-handed experience — Questions?

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.
