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
Border Pro is the photographer’s tool for adding beautiful, precise borders to your photos — whether you shoot on iPhone, mirrorless, or film. Built for people who care about their images, Border Pro preserves your EXIF data on every save. Your camera model, lens, focal length, aperture, shutter speed and date all stay intact. BORDERS THAT MEAN SOMETHING Borders are calculated as a percentage of your image, so they stay perfectly consistent across every aspect ratio and resolution — from a phone snap to a 102MP medium format file. PRINT YOUR SHOOTING DATA Turn on Metadata Print and your camera data is printed directly onto your border — just like a lab print. Choose from 20 fonts including elegant scripts, classic serifs and clean sans-serifs. Set the colour to auto or pick any custom colour. Print on any edge — bottom, top, left or right — with the weighted border following automatically. COLOUR BORDERS Choose from curated classic tones, vibrant presets, or sample any colour directly from your photo using the built-in eyedropper with magnifier loupe. Save up to 6 custom colours for quick access. SHAPE YOUR BORDERS Control each corner independently — from fully rounded to square, mixed, or anything between. Create arches, D-shapes and compositions that are entirely your own. SOCIAL MEDIA READY Export to Instagram square, portrait, landscape or Story/TikTok formats with a single tap. Preview the canvas before you save. EXPORT YOUR WAY Choose JPEG, HEIC or lossless PNG. Set your own quality level. Your images, your format. EVERYTHING ELSE • White, black and custom colour borders • Double border with custom keyline colour — black, white, or any colour • Weighted border on any edge for that classic print look • Save up to 10 named profiles, synced to iCloud • Batch export up to 100 photos at once • Works completely offline • Saves to a dedicated Border Pro album in Photos VIDEO SUPPORT Photos and videos, treated the same way. Add gallery-style borders without cropping, compression, or loss of quality. Border Pro is for photographers who want their images to look considered, not filtered.

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.

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.
