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.

DRINK RESPONSIBLY WITH PRECISION THAT MATTERS Last Pour isn't just another BAC calculator. It's the first tracking app built for people who take drinking safety seriously and refuse to gamble with guesswork. WHY LAST POUR BEATS OTHER BAC APPS Most BAC trackers fail when you need them most. They use outdated weight data, give dangerously optimistic readings, and reset randomly at midnight regardless of your actual drinking pattern. Last Pour was designed by people who understand that a 10-15 pound weight change can mean the difference between 0.02 and 0.05 BAC - the difference between safe and unsafe. FEATURES THAT KEEP YOU SAFER DYNAMIC WEIGHT UPDATES Every drinking session starts with a current weight check. Your weight fluctuates more than you think, and accurate BAC depends on getting this right every single time. CONSERVATIVE CALCULATIONS While other apps encourage risky behavior with liberal estimates, Last Pour adds a 20 percent safety buffer to all calculations. We'd rather you wait an extra hour than make a dangerous mistake. PRECISION DRINK LOGGING Log exact ounces and alcohol percentage instead of vague "one beer" entries. The difference between a 4 percent light beer and 7 percent IPA is massive for your BAC. MANUAL SESSION CONTROL You decide when your drinking session starts and ends. No more apps that randomly reset at midnight while alcohol is still in your system. REAL-TIME ELIMINATION TRACKING Watch your BAC decrease hour by hour based on proven alcohol elimination rates. Know exactly when you're approaching safe levels instead of playing guessing games. CONSTANT SAFETY REMINDERS Clear disclaimers remind you that no app replaces good judgment. These are estimates for awareness, not medical or legal advice. WHO USES LAST POUR Safety-conscious social drinkers who want to enjoy themselves responsibly without anxiety about their limits. Designated drivers who need to track their consumption precisely to ensure they can drive safely later. Anyone who has ever wondered "Am I okay to drive?" or "Should I have another drink?" and wanted a reliable answer based on science, not guesswork. THE LAST POUR DIFFERENCE Other BAC apps treat alcohol tracking like a game. Last Pour treats it like the serious safety tool it should be. We prioritize accuracy over convenience and safety over optimism. Every calculation errs on the conservative side because we know you're making real decisions with real consequences. Whether you're planning to drive home, deciding on another round, or just want awareness of your consumption, Last Pour gives you the most reliable estimates available in any consumer app. DOWNLOAD NOW AND DRINK WITH CONFIDENCE Stop gambling with inaccurate BAC guesses.

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.
