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.

Breathing flow is a personal breathing coach in your pocket. Learn breathing techniques to promote mindfulness, manage stress, sharpen your focus and find peace — wherever and whenever you need it. The key to a positive state of mind Breathing flow is designed to balance your breathing patterns using simple touch sequences. It is is based on techniques that have been used in yoga and meditation for centuries. Rhythmic breathing brings practitioners into a flow state, boosting concentration, energy levels and performance. Guided by touch Simple touch sequences create an immersive experience, enhancing your ability to be fully present and leave stress and anxiety behind. Better health in a few minutes a day breathing flow is an app designed to balance your breathing patterns using simple touch sequences. Is there science behind it? Absolutely. Multiple peer-reviewed studies show that regulating breathing patterns can help practitioners overcome anxiety, combat stress and enhance performance. Smooth, rhythmic breathing activates the parasympathetic branch of the nervous system, promoting a sense of well-being and calm — the positive mental state necessary for peak concentration and creativity. What makes it special? breathing flow works differently than other relaxation apps. The simple touch interface was designed by game industry veterans to engage multiple senses. By allowing you to touch, listen and see the breathing sequences, the experience becomes an immersive game, not a chore. How does it work? Begin by touching the screen with your inhale. Through audio and visual cues, breathing flow times the length of your inhale, and instructs you when to release your finger from the screen and exhale. After following the cycle for a few minutes, the app invites you to continue with your eyes closed, guiding you solely through audio cues. Through these exercises, you’ll learn to bring your attention back to your inner self. To break away from stressful thought patterns. To achieve a positive state of mind.

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.

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.
