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.

Crossi helps you discover the friends you've almost met before. Your camera roll already remembers where you've been. Crossi reads location data from your photo metadata (never your photos themselves) and builds a personal map of the places your life has overlapped with people you know. FIND YOUR CROSSINGS • Scan your library to uncover cities, neighborhoods, and spots you've visited • See crossings on a beautiful map. Tap any pin for who was there and when • Learn how many times you and friends were in the same place before you knew each other STAY IN THE LOOP • Get notified when you cross paths with someone so you don't miss the moment • Track your stats: locations visited, friends connected, and total crossings • Add a home screen widget to see your crossing count at a glance BUILT FOR REAL LIFE Crossi is for anyone who's ever wondered, "Wait, we were both in Vegas that summer?" Turn shared places into shared stories, and finally connect the dots on friendships that were closer than you thought. PRIVACY FIRST • We only use location metadata from your photos. We never store your photos • You control photo library access through iOS permissions • Sign in with Apple for a simple, secure account --- Crossi may offer optional in-app purchases or subscriptions.

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.
