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.

HeartDistance is a clean, minimal, and modern app designed to help you feel closer to the person who matters most to you. Whether you are in a long-distance relationship, traveling frequently, or simply spending time apart during the day, HeartDistance provides a simple and elegant way to stay connected. The app displays the real-time distance between you and your partner directly on your lock screen or home screen, creating a quiet but meaningful reminder of your connection. HeartDistance focuses on a single purpose: showing the current distance between two people in the most clear, beautiful, and distraction-free way possible. With a carefully crafted interface, smooth layout, and soft visual style, the app feels natural, calming, and thoughtfully designed. It delivers essential information in a subtle, emotionally resonant way without overwhelming the user or adding unnecessary features. After signing up, you can connect with exactly one person using a secure pairing link or code. Once connected, the app continuously updates your distance based on both users’ locations. HeartDistance calculates distance in kilometers, meters, or miles, depending on your preference. It also detects when you are physically together and displays a special "Together" status, offering a meaningful moment within everyday routines. The app includes early support for both lock screen and home screen widgets. These widgets are designed to be minimal, readable, and visually consistent with modern device aesthetics. They show your current distance and, when possible, indicate whether you are moving closer or further apart compared to your previous location update. The widgets are intentionally simple to ensure they blend seamlessly into the device environment. HeartDistance is built with privacy in mind. The app uses location data only to calculate distance between paired users and does not store long-term location history. All data is securely transmitted, and users maintain full control over permissions and visibility settings. The app avoids unnecessary tracking, analytics, and external services to ensure a private and trustworthy experience. As development continues, upcoming features will include expanded widget styles, improved distance accuracy, optional notifications, refined animations, enhanced battery efficiency, and additional customization options. These improvements will be released gradually to ensure quality, clarity, and a consistent user experience. HeartDistance is for anyone who values simplicity, emotional connection, and thoughtful design. By focusing on one meaningful feature and executing it with care, the app provides a daily reminder that distance does not have to diminish closeness. Whether you are across the city or across the world, HeartDistance offers a quiet sense of presence and connection, designed to be part of everyday life without demanding attention.

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.
