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.

Orbit is a flexible intermittent fasting companion designed to help you fast on your terms, understand your progress, and build sustainable habits. Whether you follow 16:8, 18:6, OMAD, or a custom schedule, Orbit gives you a simple fasting timer, educational metabolic phase insights, hydration and weight tracking, journaling, streaks, and Apple Health integration in one privacy-focused experience. FASTING THAT FITS YOUR LIFE • Start, pause, resume, or extend a fast whenever you need. • Choose popular fasting plans or create a schedule that works for you. • Track elapsed and remaining time with a smooth visual fasting ring. UNDERSTAND YOUR FAST Follow an educational timeline of fasting phases, including digestion, glycogen use, fat burning, ketosis, and later-stage fasting. See what may be happening during each stage and learn what to expect as your fast progresses. JOURNAL YOUR PROGRESS Keep a chronological record of completed fasts. Add mood, energy level, notes, photos, and tags so you can look back and understand your habits over time. WEIGHT & HYDRATION • Log body weight and follow trends over time. • Track progress toward your weight goal. • Quickly add 250 ml or 500 ml of water. • View hydration progress throughout the day. INSIGHTS & STREAKS Stay motivated with current and longest streaks, consistency tracking, average fasting duration, completed fasts, and personalized insights based on your history. APPLE HEALTH Sync supported body weight and dietary water data with Apple Health for a more connected health-tracking experience. YOUR DATA, YOUR JOURNEY Orbit is built with a privacy-first approach and gives you tools to export your fasting, weight, and hydration history as CSV files. Orbit is intended for educational and personal tracking purposes only and does not provide medical advice, diagnosis, or treatment. Consult a qualified healthcare professional before beginning extended fasting or making significant dietary changes.

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.
