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.

Ancient Light transforms your iPhone into a camera of the nineteenth century. Twelve authentic historic photographic processes - each faithfully simulated through the physics of tone, silver chemistry, grain, paper, emulsion, and light. Not filters. Processes. -- THE TWELVE PROCESSES -- Daguerreotype (1839) - The first successful photograph. A mirror-like silver surface with luminous shadow detail and seven scanned frame choices, plus No Frame. Tintype (1853) - The photograph of the working class. Robust, immediate, metallic, with regular or square format options and optional worn plate borders. Albumen (1850s) - Warm egg-white paper prints mounted as cabinet cards, with soft sepia-brown toning, aged cream stock, rounded corners, and a ruled inner border. Sepia - The warm brown tone of silver sulphide that preserved Victorian portraits through a century and a half. Cyanotype (1842) - Sir John Herschel's iron-based process. Deep Prussian blue. The print that gave photography the word "blueprint." Anthotype (1839) - Made from crushed plant pigments. Delicate, fugitive, botanical. The most poetic photographic process ever devised. Platinum (1873) - The process of fine art portraiture. Cool, shadow-rich, with a tonal range silver could never match. Autochrome (1907) - The Lumiere brothers' starch-grain colour process. Dreamy, pointillist, the first practical colour photography. Emulsion - A damaged instant-emulsion look with faded color, warm highlights, scorched edges, amber leaks, scratches, and oxidized surface wear. Bromoil (1907) - Oil-based ink on bleached gelatin. Painterly and stippled, with inky shadows and pale milky highlights. Lippmann (1891) - Gabriel Lippmann's Nobel Prize-winning interferential process. Warm amber ageing, long-exposure softness, and glass plate scratches from a century of handling. Infrared (1930s) - Light beyond the visible spectrum. Luminous white foliage, darkened skies, ethereal skin tones. The spectral world captured on heat-sensitive emulsion. -- WHAT ANCIENT LIGHT CAN DO -- * All four optical lenses - ultrawide (0.5x), wide (1x), 2x, and telephoto (5x) - selectable from the viewfinder * Shoot once, save many - save multiple historic versions from a single capture * On iPhone Pro: saves both a filtered JPEG and the original 48MP ProRAW DNG as a paired asset * Emulsion process with faded instant-film color, warmer highlights, lighter grain, and scanned edge damage * Albumen cabinet-card output with warm paper tone, aged stock texture, rounded card corners, and ruled border * Infrared process with glowing foliage, dark skies, and spectral black-and-white tonality * Tintype options - choose regular or square format, with period borders or no borders * Seven Daguerreotype frame styles plus No Frame, selectable directly from the viewfinder * Higher-resolution Daguerreotype frame output, scaled to the photo instead of the source frame artwork * Adjustments apply to the photograph while preserving Daguerreotype frame artwork * Full adjustment suite - exposure, contrast, highlights, shadows, black point, saturation, vibrance, warmth, sharpness, and vignette * Auto enhancement with one tap * Precision crop tool with inset handles and rule-of-thirds grid * Landscape side-panel layout keeps the image large while all controls stay accessible * Photographer credit field - your name travels with every saved file in the IPTC metadata * Process, frame, and Tintype options stored between sessions * iPhone and iPad, all orientations * No subscription. No ads. No account required. Ancient Light is a single purchase. Everything in it is yours.

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.
