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
See the Northern Lights with confidence — not by luck. AuroraMe is your aurora borealis tracker combining real-time space weather, cloud coverage, moon phase, and local darkness into clear visibility forecasts. Track locations worldwide on an interactive 3D globe and get notified only when conditions align for actual aurora viewing. 3D GLOBE AURORA MAP See real-time aurora activity across the planet on an interactive globe. Toggle aurora probability heatmap overlay to spot where the lights are dancing now. Switch between dark and NASA satellite night themes. Day/night terminator zones show viewing windows instantly. Tap anywhere on the globe to check aurora probability and add tracking locations. AURORA SCORE Aurora Score combines space weather, magnetic latitude, darkness, clouds, and moonlight into a 0–100 viewing score. It is a model score, not a calibrated probability. SMART AURORA ALERTS Alerts are sent only for your active locations. We factor in darkness, cloud cover, moonlight, and geomagnetic activity, so an alert means a high chance, not a 100% guarantee. Forecast, storm, KP, and solar flare alerts are heads-ups to get ready. Before heading out, open the map to confirm conditions. 72-HOUR FORECAST Hourly aurora predictions paired with weather data. See cloud percentage, moon phase, darkness windows, and temperature hour-by-hour. Use "Best Time" filter to show only optimal aurora viewing hours. Free users: 24-hour preview. Premium: full 72-hour detailed forecast with extended planning. 27-DAY TREND CALENDAR Daily aurora activity summaries for trip planning. Shows best 6-hour viewing windows per day. Excludes unreliable long-range weather predictions to prevent false hopes. Perfect for planning aurora hunting expeditions and photography trips weeks ahead. AURORA HISTORY 11 years of history and Sun Pro insights. Best months algorithm shows optimal times to visit any location. Calendar heatmap displays 12 months of aurora intensity patterns. FIND NEAREST AURORA Discover active aurora within 2000 km of your location. Distance-first algorithm finds the nearest visible displays for spontaneous aurora chasing. Perfect for road trips when conditions shift unexpectedly. 67,500+ LOCATIONS OFFLINE Search cities across 252 countries with instant offline results. Track unlimited locations with independent notification settings for each. No background GPS tracking — your privacy protected. HOW IT WORKS Four reality factors combined: space weather from NOAA OVATION model + real-time KP index, cloud coverage forecasts, sun altitude and moon illumination, magnetic latitude thresholds. When all factors align during dark hours with clear skies, you get notified. FOR AURORA HUNTERS & PHOTOGRAPHERS Whether in Alaska, Canada, Iceland, Norway, Sweden, Finland, Scotland, or northern US — avoid wasted drives and cloudy nights. Save viewing spots, set alert sensitivity, let the app monitor conditions 24/7. Photographers get probability data for optimal shooting windows. FREE — EVERYTHING YOU NEED 1 location, full 24-hour forecast, unlimited aurora & storm & Kp & solar flare alerts, all 6 map overlays, data updated every 15 minutes. PREMIUM — FOR AURORA CHASERS Unlimited locations worldwide, 72-hour forecast, 27-day trip planner calendar, Best Time filter, Best Month & seasonal heatmap, Nearest Aurora finder, advanced alerts (predictive, Storm Watch, CME Impact ETA, Local Window, Weekly Forecast), Sun Pro AI-powered solar analytics.

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.
