Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Lycana is your intelligent lupus companion — designed specifically for people living with Systemic Lupus Erythematosus (SLE) and related autoimmune conditions. SMART MEDICATION MANAGEMENT Never miss a dose. Lycana optimizes medication timing based on food interactions, absorption windows, and your daily routine. Get drug-drug, drug-supplement, and drug-food interaction warnings. Photosensitivity alerts combine your medications with real-time UV data to keep you safe outdoors. SYMPTOM & FLARE TRACKING Log symptoms quickly with an interface designed for tough days. Use the interactive body map to tap exactly where it hurts across 16 body zones. Quick Check-in gets you logged in under 2 minutes. Attach photos to track rash progression and compare before-and-after side by side for doctor visits. FLARE RISK PREDICTION A flare risk score (0-100) combines symptom logs, wearable data, lab trends, and weather patterns to spot flares before they happen. Discover personal weather-symptom correlations — see how UV, pressure, and humidity affect your symptoms over time. LAB INSIGHTS Log and visualize complement levels (C3, C4), anti-dsDNA, CBC, CRP, ESR, and more. See trends and understand what your numbers mean for lupus management. LUNA — YOUR AI HEALTH COACH Meet Luna, your on-device AI companion. Get meal suggestions, health guidance, and encouragement on tough days — all while being reminded to consult your healthcare provider. WEARABLE INTEGRATION Connect Apple Health for heart rate, HRV, sleep, steps, blood oxygen, skin temperature, blood pressure, respiratory rate, blood glucose, and menstrual cycle tracking. These signals power more accurate flare predictions. CARE TEAM SHARING Invite family or caregivers to see selected health updates — medication adherence, flare risk, labs, or symptoms. You control what they see. Diary and mental health data are never shared. Generate encrypted health summaries and visit prep checklists for your doctor. SMART REMINDERS Adaptive notifications learn from your patterns — worst-day warnings, HRV drop alerts, adaptive medication timing, and sleep-adjusted quiet hours. SIRI & SPOTLIGHT Log food, start check-ins, check medications, and get insights by voice. Search your medications and doctors from Spotlight. MENTAL HEALTH SCREENING Track emotional wellbeing with validated tools (PHQ-2, PHQ-9, GAD-7) alongside your physical symptoms. RESEARCH PARTICIPATION Enroll in lupus studies, complete validated surveys (FACIT-Fatigue, LupusPRO), and donate anonymized data to advance lupus research. PRIVACY FIRST Health data stays encrypted on your device using the iOS Keychain. We never sell your data or store health records on our servers. No email needed to get started. --- Lycana is NOT a medical device and does not provide medical advice. Always consult your rheumatologist or healthcare provider for medical decisions.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
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.
