Generating… usually about a minute.
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.

This CheckPad is the same one that was in the AppStore till October 2020 Created a macOS version from iOS version via Mac Catalyst. Same UI and some macOS menu options. macOS Catalina (version 10.15) is required to run this macOS version. Payer/Payee changed to From/To. Date, Means, From/To and Memo fields changed from center to left aligned. Fixed bug with searching for From/To. Allows deletion of iCloud accounts in Settings. Since Bundle ID has changed, users need to save to device and move to desktop and then copy to new app. ATTENTION:USERS OF PREVIOUS VERSIONS WHO USE iCloud MUST READ THIS BEFORE UPDATING. Due to an App identifying change, save your data to iCloud, or save them in Finder (in Catalina) to any location and add them to this version. CheckPad is a simple digital version of a check book. Transactions are presented on the screen the same way they are in a check book register. This is not an online bill payment application and therefore doesn’t have access to any bank data via the internet. It replaces most of the paper in your drawers, shoe box and on your desks. With this app you can keep track of your money by tracking transactions like you normally do with your checkbook. CheckPad offers the following advantages: - help save the trees - Printing now supported despite the app premise. Some users just can't do without a hard copy. - make clean transaction register entries without messy corrections - correct transaction dates - familiar layout - so simple to use an 8 year old (who keeps a register) can use it without help - offers password protection to prevent unauthorized access - a small memory foot print and fast - doesn’t require the internet to use it (except backing up accounts to iCloud)

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.
