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.

Night Camera HD - the expert for professional nighttime shots on iPhone, iPad and iPod touch. AppAdvice 4.5/5 stars review: "Night Camera HD is a tool that every inclined mobile photographer should have." Thanks to the manual setting options for light exposure up to 1 second *, separate residual light- and ISO enhancement, Night Camera HD is perfect for taking pictures in a dark, insufficiently lit environment. Even during daylight, your pictures are clearer, with less interference, due to the extended exposure times. Take high-resolution photos in PNG format without visual loss. Forget about the loss of quality experienced with other cameras apps caused by image compression artifacts. Regardless whether you take night-, scenery- or other photographs, the picture quality you are able to achieve with Night Camera HD will surprise you. You can easy tap to focus and tap to exposure at the same time. After selecting the desired setting, you can easily lock it to prevent changes despite movement. Only here you can get luminance, luminosity and RGB histograms in real time to recognize over- and underexposure in time. The self-timer, which is imperative for nighttime shots, enables you to take un-blurred pictures. With the aid of the volume buttons you can take pictures with volume up (+) and fade the HUD-elements in- and out with volume down (-). Of course you can also block the white balance separately and edit it if necessary. Standard image formats (4:3, 3:2, 1:1, 16:9 and 3:1) can be edited live. The full-screen mode is activated for narrow image formats, enabling maximum display use. This feature can also be deactivated. The histogram adapts to all image formats. The up to 6x digital live zoom can be edited in the settings to enable a greater precision level during targeted zooming. Of course diverse alignment grids (e.g. Rule of Thirds, Golden Spirals and Golden Triangle) as well as a virtual horizon are available as overlays. Various real-time color filters complete this app. The most important functions: - Shutter speed control - Up to 1 second * exposure time - Manual ISO setting - Manual focus - Residual light enhancement - Real-time luminance histogram - Real-time luminosity histogram - Real-time RGB histogram - Self-timer - Volume Up (+) Photo Capture - Volume Down (-) HUD Hide - 6x digital live zoom - Tap to focus - Tap to exposure - White balance-lock - Manual white balance - Manual exposure adjustment - Various alignment grids - Virtual horizon - Aspect ratios: 4:3, 3:2, 1:1, 16:9 and 3:1 - Full-screen mode - Eco mode - Diverse color filters in real-time - Take HD photos - Landscape and portrait mode - Supports front and back camera - Supports LED-continuous light - Supports EXIF-data - Supports sharing via Facebook, Twitter *) Only on supported devices ---------- Please note that a minimum amount of light is still required. For delayed exposure times the preview is also delayed accordingly. We recommend stabilizing the device or a steady hand for taking optimal pictures with long light exposure times. ---------- Follow @NightCameraHD on Twitter and don’t forget to tag your photographs with #NightCameraHD.

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.
