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.

Every meeting has a price tag. Wasteclock shows it to you live, in real dollars, while the meeting is still running. Enter how many people are in the room and what they cost (hourly rate, or an annual salary, which Wasteclock converts automatically), hit start, and watch the number climb. When it crosses $500, it turns red. When the meeting's over, share the total with one tap. WHY WASTECLOCK Meetings are one of the only business expenses nobody actually sees. Wasteclock makes the cost visible in the moment it's happening, not in a spreadsheet three weeks later. FEATURES • Live running cost, updated every second, rounded to the nearest dollar • Headcount slider: 1 to 100 people, with precise +/- controls • Hourly or salary-based rate, with automatic salary-to-hourly conversion • Color changes to red past $500 so the stakes are impossible to miss • Pause and resume anytime, with automatic pause if you leave the app • Edit headcount or rate mid-meeting without losing your place • One-tap share of the final cost, duration, headcount, and rate • Full light and dark mode support FREE TO TRY Your first 2 meetings are free. After that, a single one-time purchase unlocks unlimited meetings — no subscription, ever. PRIVACY, DONE RIGHT Wasteclock has no backend, no accounts, no analytics, and no ads. Nothing you enter ever leaves your phone.

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.

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.
