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.

CalmingVibration – Soothe Stress with Your Apple Watch Discover a moment of calm with CalmingVibration, the innovative WatchOS app designed to help you manage stress. Harnessing the power of your Apple Watch’s haptic engine, CalmingVibration delivers gentle, rhythmic vibrations to promote relaxation (or focus) and restore balance, right from your wrist. Why CalmingVibration? Personalized Stress Relief: Using HealthKit data like Heart Rate Variability (HRV) and Resting Heart Rate (RHR), CalmingVibration intelligently detects stress levels in real-time and suggests soothing haptic sessions tailored to your needs. Our app uses carefully crafted haptic patterns to calm your nervous system, helping you feel centred. Seamless Integration: Fully compatible with WatchOS 10 and above, CalmingVibration taps into Apple’s HealthKit to monitor your stress indicators and provide actionable insights. Customizable Experience: Adjust session durations, session types (will change the haptic feedback accordingly) and stress detection settings to match your preferences. Choose intelligent learning-derived baselines or custom thresholds for a truly personalized experience. Real-Time Stress Monitoring: Stay informed with real-time updates on your stress levels, displayed with intuitive emojis and color-coded feedback. Key Features: Haptic-Driven Relaxation: Enjoy customizable vibration patterns to ease stress, from gentle clicks to soothing success haptics. Smart Stress Detection: Leverage HRV and RHR data to identify high or moderate stress levels and receive proactive suggestions for calming or focus sessions. After each session, connect with the Mindfulness app to track your progress and stress levels. User-Friendly Interface: A sleek, intuitive design with a pulsating animation to guide you through sessions, plus easy access to settings for a tailored experience. How It Works: Monitor: CalmingVibration uses HealthKit to track your HRV and RHR, calculating your stress level based on customisable or derived baselines. Relax/Focus: Start a session (1–5 minutes) with specific haptic feedback designed to soothe your nervous system. Reflect: After each session, check your stress levels in the Mindfulness app to see the difference and allow your Apple Watch to re-calculate your HRV and update your RHR [Apologies, Apple (still) doesn't provide an API to trigger that calculation from the App]. Perfect for Everyone Whether you’re navigating a busy workday, preparing for a big moment, or simply seeking a moment of peace, CalmingVibration is your companion for stress relief on the go. Designed for WatchOS 10+, it’s optimized for seamless performance on your Apple Watch. Download CalmingVibration today and feel the difference a moment of calm can make! Notes CalmingVibration requires access to HealthKit for HRV and RHR data. Ensure your Apple Watch is running WatchOS 10 or later for the best experience. Prolonged usage of the haptic feedback may drain the Apple Watch battery. Health claims are not verified by the FDA and are not intended for medical purposes.

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.
