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.

Pick a photo. Set the size. Place it on the page. Print. It sounds simple because it is. PrintScale does the one thing your phone can't: print a photo at the exact physical size you choose. No guessing, no trial and error, no wasted paper. Choose any photo from your library, drag it where you want on the page, set the exact width in millimeters or inches, and hit print. What you see on screen is exactly what comes out of your printer. Pay once, unlock everything. No subscriptions, no in-app purchases, no locked features. PRINT PASSPORT & ID PHOTOS AT HOME Stop paying for overpriced passport photo services. Select your photo, tap the passport preset (35x45mm), and PrintScale automatically crops and sizes it to meet official requirements. Print a full sheet of passport-size or ID-size photos in seconds — ready for your application. THREE STEPS TO A PERFECT PRINT 1. Pick a photo from your library 2. Set the size — type exact dimensions, use a preset, or pinch to resize 3. Tap print — done PUT MULTIPLE PHOTOS ON ONE PAGE Arrange several photos on a single sheet — place them freely or use built-in templates. Passport grids, wallet-size sheets, ID card layouts — all with one tap. Drag photos anywhere on the page and they snap into place. SIZE WITH PRECISION - Slider, presets, or pinch gesture — three ways to set the exact size - Built-in presets: 4x6", 5x7", 8x10", passport, ID card, and more - Real-time DPI indicator tells you if your photo is sharp enough before you print - Millimeters or inches — your choice PRINT BIGGER THAN YOUR PAPER Need a poster? Enable tiling and PrintScale splits your image across multiple pages with alignment marks so you can piece them together. CROP, FILTER & ADJUST Crop to any ratio, apply filters (B&W, Sepia, Vivid, Noir), and rotate — all without leaving the app. PRINT OR SAVE AS PDF Send to any AirPrint printer or export a PDF. Supports A3, A4, A5, US Letter, US Legal, and custom paper sizes in portrait or landscape. Save your projects and come back to them anytime. Full undo/redo for every action. Works on iPhone and iPad. Available in English and Spanish.

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.
