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.

Pregmate is an ovulation tracker, period tracker, and pregnancy app for women who want to know what's happening with their cycle, not guess. Track your period, find your fertile window, scan your ovulation tests, and follow your pregnancy week by week. All in one app. What's inside Pregmate tracks your full cycle from period to pregnancy without asking you to switch apps. Your data stays in one place from the first period you log to your due date. • Ovulation test scanner that reads any LH strip and shows your T/C ratio, a number that tells you how close you are to your LH peak • Ovulation tracker with predictions that learn from your real test results, not just calendar averages • Period tracker with cycle forecasts that get more accurate the more you log • Pregnancy test log to save photos with date and DPO context, so you can compare line progression cycle to cycle • BBT charting, cervical mucus, and 30+ symptoms • Intercourse log for TTC timing • Pregnancy mode that activates after your positive test • Reminders for tests, fertile window, and period Stop second-guessing faint lines You don't have to decide whether a line is dark enough. Open the scanner, point your phone at your LH strip, and Pregmate reads both lines for you. You get a positive or negative right away, plus the T/C ratio. Every scan is saved with the photo, cycle day, and date, so you can watch your surge build day by day. The scanner is built primarily for Pregmate strips, but works with most standard LH strips on the market. How does Pregmate help you get pregnant? The more you log, the better your fertile window predictions become. Pregmate combines your real test results, BBT, cervical mucus, and cycle history to find your most fertile days. That's the timing window TTC users care about most. What happens after a positive pregnancy test? Pregmate switches into pregnancy mode. Your due date gets calculated from your last period, you track each week as your pregnancy progresses, and your TTC history stays right where it was. You don't start over, and you don't need a separate pregnancy app. Your data stays private Pregmate doesn't sell your data. Every scan, photo, and log is yours, and you can delete any entry whenever you want.

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.
