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.

Camera1 is the dedicated Black & White manual camera for iPhone. No colour, no compromise — just pure monochrome photography with full creative control. DEVELOP YOUR CREATIVITY Learn to "see" in Black & White through Camera1 unique simultaneous contrast and exposure adjustments. Explore the infinite black and white image possibilities in real-time, such as high-key/low-key right in the viewfinder, before taking the shot. Use the Zen mode to focus all your creative attention on the picture, and not the camera or technique. TAKE CONTROL Take control of the camera, with manual overrides of exposure and focus. Super easy access to focus lock using the manual focusing slider, for ultra-fast shooting - as the camera won’t need to re-focus between shots. PROFESSIONAL OUTPUT Camera1 takes full advantage of your camera hardware and saves in a variety of different file formats, including JPEG, TIFF, RAW & ProRAW / DNG, allowing for maximum editing flexibility in applications like Photoshop and Lightroom later in your workflow. Advanced iOS image processing such as Deep Fusion and Smart HDR is used on supported devices. Live histograms, flash, grid views and a range of manual controls allow you to get the perfect shot, every time.

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.
