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.

WristRef is the perfect way to keep score and time for any professional sport or weekend shenanigans! Your iPhone never needs to be present, so there's no extra pocket weight for referees that may also be players! The easiest solution to scorekeeping and undoubtedly the most beautiful. WristRef lives on your wrist so it's always in the game. Every pixel and feature was carefully crafted for casual or professional Apple Watch users. Fingers will agree, your wrist keeps count much better than they ever could! - Setup WristRef for any competitive game or sport with the new Settings menu. Discover a new sense of precision with milliseconds or switch back to classic mode. - Name either team by Force Touching their scorecard and tapping the microphone, emoji, or preset name options! - Tap a team's Color Bar to loop through 15 different colors. Glide across the Digital Crown with precision to scroll back and forth without looping! - Press play from "00:00:00" to start the stopwatch or use the "+/-" hour and minute buttons to set the timer. With the timer set, press play to start counting down! - Force Touching the Scoreboard will present the "00:00:00" and "RESET" menu options. Tapping the X will reset the clock to "00:00:00" while tapping the trash can will reset both score and time! - Enable WristRef's Glance in the "Apple Watch" app on your iPhone for a quick peak at the current game. Just in case the score and time aren't the first things you see when you raise your wrist!

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.
