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.

Calculate what percentage each act is of the total. Figure total run time, total content time, and how far over or under time the project is. Runtime is an easy and fun way to keep track of your film, tv or radio project. • calculate Total Runtime or Total Content Time • automatically figures how over or under time a project is • visually see your timings with the bar graph • email timings to co-workers with one tap • support for multiple projects • 23.98, 24, 25, 29.97, 30, 59.94 and 60 fps all supported • the least annoying timecode entry you'll find in the App Store! • timer for timing segments live on set • a no-nonsense tool for professionals Editors, producers, preditors, and post supervisors all over the world have embraced Runtime's simple solution to a complex problem. PLEASE NOTE: Runtime was created for editors who add times together to get a total. Need timecode multiplication? Timecode division? Runtime isn't for you.

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.
