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.

Visualize Your Shift Schedule From Jeff: Please don't put questions or suggestions in a review -- there's no way for me to reply directly to you. Instead. use the in-app email buttons (on the Help tab), or send to [email protected]. If your schedule varies from week to week, keeping track of your working days can be a chore, and it’s often difficult to quickly figure out when you’ll be on-duty weeks or months in the future. Scheduler to the rescue! Designed for public-service employees such as police officers, firefighters and health-care workers — anyone who works an unusual but predictable schedule — Scheduler always shows your schedule for the next six years from “today.” Common shift schedules are built-in, such as the “Berkeley” (a.k.a. “California”), “48-96” and “Dupont,” but you can easily change them or create other repeating schedules covering any number of days. See the screenshots (here and on the web site) for some examples. And there’s even a “Doofus” mode for showing irregular schedules (e.g., health-care workers). If your spouse/partner works a shift schedule, too, you can have that entirely different rotation appear on the calendar with yours. This will help you organize family activities such as vacations and day-care. Features: • Displays your schedule for the next six years, including vacations and holidays. • Perfect for public-service workers such as police officers and firefighters. • Records trades (swaps). Tracks hours earned or owed on a person-by-person basis. • Formats emails for sending out trade offers and approval requests. • Maintains a record of your OT hours. • Tracks your vacation time: automatically computes hours earned and shows weekly balances. Also records and totals sick time. • Logs “events” with date, time and location — you can edit the title, text, and location details when you have time. • Overlays an entirely separate schedule for your spouse/partner to help you coordinate your lives. • Adjustable colors for shifts, vacations, Kelly days, holidays, etc. • Mark special days such as Kellys, paydays, “early” shifts, or training days. • Countdown to retirement. • Extensive Help pages for every feature and screen; indexed. • Includes UK Rota features for London train and bus drivers. Notes: 1. You *can* enter a custom schedule. 2. You *can* set the text that appears on each day. 3. You *can* enter very long rotations. 4. You *can* superimpose text to mark special days on the calendar. 5. You *can* set bi-weekly repeating events (e.g., for paydays) 6. Scheduler is complicated. Please don't give up and leave a bad review -- I can't help you that way. If you have questions or comments, the best way to contact me is by using the in-app email button on the Help screen (2nd best: [email protected]). I reply to all emails immediately (or within a few hours if I'm sleeping or traveling, which isn't often). If you didn't hear from me promptly, it means there was failure in the "Tubes." Please try again to contact me. Attention FDNY (firemen): you'll find my other app, FDNY, more useful for FD New York.

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.
