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.

Job Clock Tracker — Time tracking for people who bill by the hour A no-nonsense stopwatch for contractors, freelancers, and small business owners who need to track billable time accurately, without the bloat of a full project-management suite. Features Simple timer, powerful tracking Pick a client, pick a project, tap play. That's it. Stop when you're done. The app records your hours down to the hundredth so nothing falls through the cracks. Lock screen Live Activity See your running timer right on your lock screen without unlocking your phone. Glance at your elapsed time in seconds. Survives force-quit and restart Accidentally close the app or restart your phone mid-session? Your timer keeps running. When you reopen, you're taken straight back to the running timer. Per-project hourly rates Set a different rate for every project. The app calculates earnings automatically as you work. Filterable history View totals grouped by client and project, or scroll every individual entry. Filter by Today, This Week, Last Week, This Month, Last Month, This Year, All Time, or a custom date range. Editable entries Forgot to stop the timer? Tap any history entry to adjust start and end times. Email reports Generate professional time reports for any set of clients over any date range. Includes totals, per-entry breakdowns, and earnings — sent from your default Mail app. Google Calendar sync (optional) Sign in with Google and stopping the timer automatically creates or updates a single summary event per day on your chosen calendar. Perfect for keeping a visual record of your billable work alongside your regular schedule. Backup and restore Save a backup file to the iOS Files app (iCloud Drive, On My iPhone, or anywhere Files supports). Restore anytime. Notes per project Keep project-specific notes right on the timer screen. Perfect for job codes, client instructions, or things to remember. Privacy-first Your data stays on your device. We don't operate any servers that collect or store user data. Google Calendar sync (when enabled) sends data directly between your device and Google — never through us. Built by a contractor for contractors. If it's not something you'd use yourself, it's not in the app.

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.
