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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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.

Follow the movement of Mars, Jupiter, and Saturn, billion stars or discover deep-sky objects like galaxies and nebulae. - Meet Astra — Your AI Astronomy Guide Ask anything about the universe and get instant, easy-to-understand answers. Why is Mars red? What is a black hole? When will the next eclipse happen? Astra explains stars, planets, galaxies, missions, and cosmic phenomena in plain language — perfect for curious minds, students, and lifelong learners alike. Tap any object in the sky map and let Astra tell you its story. - Live Universe Calendar Never miss a cosmic moment again.

See exactly when, where, and how to watch each event. - Real-Time Event Notifications Get alerted before the sky puts on a show. Receive timely reminders for upcoming meteor showers, eclipses, bright satellite passes, and rare planetary alignments, so you are always outside and looking up at the right moment. - Key Features • Explore a precise, real-time sky map of stars, planets, and the Moon for any chosen date, time, and geographic position. • Browse a curated catalog of bright stars, nebulae, galaxies, clusters, and other notable deep-sky objects. • Smoothly enlarge detailed imagery of the Milky Way and selected deep-sky targets. • Switch between multiple constellation line styles and artwork from a variety of cultural sky traditions. • Follow artificial satellites in orbit, including major stations and bright passes. • View natural-looking horizons with atmospheric tint, daylight progression, twilight, and refraction effects. • Inspect 3D models of principal solar system bodies and their major moons. • Protect dark adaptation using an optional red-tinted night display mode. • Access an extended universe: extremely deep star catalogs, millions of galaxies, nebulae, and clusters, plus comets, minor planets and large asteroid sets. • Perform near‑limitless zoom into high‑resolution surface and deep‑sky imagery. • Operate fully offline with a compact onboard dataset (millions of stars and deep‑sky objects plus key solar system bodies). • Plan observing sessions with tools to evaluate visibility windows, altitude curves, and transit times. • Control compatible telescopes directly from the app (Meade LX200, Celestron NexStar, and RTS2), with tap-to-slew GoTo pointing. - Why Choose Stargazing: Stars & Planets?

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.
