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.

STREAKS. The habit tracker that helps you build good habits and break bad ones. Apple Design Award winner. Choose up to 24 habits you want to keep, and build a streak of days in a row. Streaks works on iPhone, iPad, Apple Watch, Mac and Apple Vision Pro, and keeps everything in sync with iCloud.

Streaks helped me to quit smoking by reducing and then eliminating my daily use.” - Ben, Adelaide. ON EVERY APPLE DEVICE * Interactive widgets for your Home Screen and Lock Screen let you complete habits without opening the app * A full Apple Watch app, with complications for every watch face * Siri and Shortcuts support * Share a habit with a friend or family member who also uses Streaks, so they can encourage you and keep you accountable MAKE IT YOURS * Over 30 color themes, including animated themes and seasonal looks * Over 800 habit icons * The Gold theme celebrates the days you complete every habit * Statistics for your current and best streaks, completion rates and history “I've now reduced my coffee intake by 70% with Streaks, something I struggled with for 5 years. It's a life changing app to me.” - Otávio, Chicago. FREQUENTLY ASKED QUESTIONS Do I need an account? No. There's no sign-up or login.

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.
