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.

Haptics Feedback is powerful tool designed for developers and enthusiasts who want to perfect the tactile experiences on iPhone, iPad, and Apple Watch. Why Haptics Feedback? Haptics are an essential part of any modern app, enhancing user engagement by adding physical responses to actions like taps, swipes, or alerts. With Haptics Feedback, you can easily experiment with different types of haptic responses, see how they feel in real time, and get the code snippets you need to implement them in your own projects. Key Features: 1. Comprehensive Haptic Testing: Test the full range of haptic feedback types on iOS and watchOS devices, including: 2. Advanced Haptics Visualizer: For developers who want to dive deeper into the haptics design process, the Advanced View offers a powerful visual representation of the haptic feedback. 3. Apple Watch Haptics Testing: Designing an Apple Watch app or extension? Haptics Feedback offers a seamless way to test and adjust haptics directly on your Apple Watch. Get hands-on with real-time feedback on your wrist. Not wearing your watch? No problem! Use the built-in Apple Watch Haptics Simulator right on your iPhone to see how haptics would perform on the watch. 4. Developer-Focused Design: Haptics Feedback is tailored specifically for developers, providing not only the tools to test and visualize haptics, but also the code snippets needed to implement them. Each feature has been designed to simplify the process of adding haptics to your apps, reducing guesswork and saving you time. Who Is This App For? - App Developers: Enhance the user experience in your apps by integrating perfect haptics that match every action. - Game Developers: Craft immersive and tactile game experiences that pull players deeper into your game world. - UX/UI Designers: Experiment with haptics to bring your interface designs to life and create memorable interactions. - Tech Enthusiasts: Discover how haptic feedback works, experiment with different styles, and learn how to bring a professional touch to app interactions. Why Haptics Matter Imagine pressing a button in your app and feeling a subtle vibration that confirms your action, or getting an alert on your Apple Watch that not only makes a sound but gives you a tap on your wrist. These sensations create a more intuitive, engaging, and satisfying user experience. With Haptics Feedback, you can test these scenarios and make sure they feel just right before adding them to your app.

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.
