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.

What better way to keep abreast of current conditions than with a beautiful METAR widget, right on your home screen? Although these widgets look simple, they’ve been carefully designed and built to give you the most important information at a glance, while meshing seamlessly with iOS17’s features and design language. Here are a few of the things that make these widgets special: THEMES Choose a subtle theme that looks right at home on your iPhone or iPad, or a more bold and colorful theme that catches your eye more effectively. SMART… Each widget can figure out what weather factors to display. Generally, special weather conditions (e.g. rain, show, haze, smoke, tornadoes) take precedence, followed by any conditions that caused the current flight condition, like low cloud bases or limited visibility. Wind is always visible. … OR NOT Alternatively, you can use the “Retro” theme to display raw METAR text and practice your interpretation skills (great for exam prep). Protip - put both widget types in a Stack (drag one on top of the other), so you can flip between them! REALTIME All METAR widgets update in realtime, in the background. You can force a refresh anytime by simply launching the app. DARK MODE Widgets seamlessly follow the system-wide light/dark mode setting, which means they’ll be easier on your eyes once the sun goes down. Also, all colors across the app and widgets have been tuned to reduce eye strain when viewing in low-light conditions. FULL METAR VIEW Tap on any widget to launch the app and view the full details. Here, you can also toggle between visual and text modes. SAVE YOUR FAVORITE STATIONS You can save and manage your favorite stations in the app, which makes it even faster to set up a new widget. Thanks for reading this far! I’m an experienced software developer and a new PPL, and I built this while learning to fly in a J-3 cub. All proceeds will go to tailwheel time, and any feedback/reviews are much appreciated!

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.
