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.

There's a moment in every day when light changes everything. Golden hour makes any photo epic. Blue hour turns a city into a postcard. And most of us miss them — because we don't know when they happen. RE LUMINARY tells you. Open the app and watch the sun live on your horizon: where it is now, where it's moving, how long until the next magical light of the day. All calculated on your iPhone with real astronomical precision — offline, no account, no sharing your location with anyone. WHO THIS APP IS FOR - Photographers who know light is everything - Filmmakers planning outdoor shoots - Hikers who want to leave at sunrise and return before dusk - Architects and designers working with natural light - Anyone who feels something when the sky turns orange WHAT YOU'LL FIND Live solar clock The sun moves on your screen based on your location. See its elevation, direction (azimuth) and predicted path for the day. Precise magic hours Dawn, sunrise, morning golden hour, soft midday light, evening golden hour, blue hour and sunset. With start time, end time and exact duration. Light quality prediction The app scores every light window from 1 to 10 based on the day's solar path. In winter near the poles, golden hour lasts hours. In equatorial summer, minutes. Your iPhone knows and tells you. Home screen widgets Three different widgets: next solar event, full day timeline and lock screen widget. See how long until next golden hour without opening the app. Dynamic Island Live Activities When golden hour approaches, your iPhone tells you from the lock screen. Live countdown. You won't miss it even with your phone in your pocket. Works without internet Calculations are local. Mountain, desert, airplane — it doesn't matter. The app works in airplane mode. No accounts, no tracking Your location stays on your device. No accounts, no servers, no ads. RE LUMINARY is designed for those who know light isn't a detail. It's the subject. Created by Resonancia Éter. Note: Astronomical calculations are precise but do not replace professional equipment for critical safety applications.

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.
