Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Turn Everyday Moments into Timeless Memories Frame everyday scenes and travel memories with your favorite composition and color, and transform each moment into something unforgettable. This camera app lets you shoot exactly as you see through a camera viewfinder. Crop your composition in real time and capture it with your own custom look—so your photos are ready the moment you press the shutter. No editing required. Features * Choose from multiple focal lengths (35mm equivalent*) as if you’re switching between prime lenses on a camera. * Select from four beautifully crafted filters: Std, B&W, Warm, and Cool. * Fine-tune the contrast, saturation, highlights, and shadows of each filter to create your own signature look. * Record video instantly by simply pressing the red REC button—no need to switch camera modes. * Capture Live Photos. * Adjust the aperture (f-stop) to create beautiful background blur. * Record videos in 4K or Full HD at 30 fps or 24 fps. * Turn HDR (High Dynamic Range) capture on or off. * Take photos with a silent shutter. * Save both your customized photo and the original unedited image at the same time (optional in Settings). How to Use 1. Select a focal length (35mm equivalent*). 2. Check the semi-transparent framing guide. * Double-tap the screen to zoom into the selected frame for a closer preview. 3. Compose your shot. 4. Tap the subject to lock focus. 5. Adjust the exposure (EV). 6. Press the shutter button. Notes * Photos are saved to Apple’s built-in Photos app. * This app does not include an image preview gallery. Please use the Photos app to view your captured photos. * Videos are always recorded in a 16:9 aspect ratio, regardless of the selected photo aspect ratio. * Photos are saved after being cropped to the selected frame. As a result, image resolution may be reduced at certain focal lengths. Please keep this in mind if you plan to print your photos. * Focal lengths are approximate 35mm-equivalent values and are provided for reference only.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
