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.

App Store description

Monitor recent earthquakes in the United States and around the world from a single screen using seismic data gathered from multiple trusted sources. View earthquakes on the map and access detailed information such as magnitude, depth, distance from your location, and potential effects. Get real-time alerts and critical notifications - with three customizable filters. If you feel an earthquake, use the SOS feature to notify your loved ones that you’re safe or in need of help — instantly with one tap. Without an internet connection, you can alert nearby people to your location by playing a specially designed whistle sound (2–4 kHz range – the most audible frequency range), which is attention-grabbing yet not harmful to human ears. Key Features: • Real-time notifications based on your preferences: - Filter by magnitude - Filter by region (continent, country, city) - Filter by distance from your location - Receive critical alerts that bypass silent or Do Not Disturb mode • View earthquakes on list and map • Filter earthquakes instantly by continent, country, and magnitude • Access verified data from trusted sources (U.S. Geological Survey (USGS), European-Mediterranean Seismological Centre (EMSC), GeoScience Australia, GNS Science (GeoNet), Japan Meteorological Agency (JMA)) • View magnitude, depth, distance, and time details in a single screen • Use SOS feature to notify loved ones with one tap • Share location with whistle sound even without internet • Search past earthquakes by date range, region, and magnitude • Share earthquake details via social media or messaging apps • Available in dark and light modes on iPhone, iPad, and macOS • Available multi language. English, Turkish, German, French, Arabic, Japanese, Chines (Simplified), Greek, Korean and Spanish This app is perfect for those living in earthquake-prone areas, frequent travelers, emergency preppers, or anyone interested in scientific earthquake data. Ad-supported version. Privacy & Permissions: The app only asks for location and notification permissions to deliver personalized alerts. Your data remains private and is never shared. SOS contacts are securely stored on your device. Privacy Policy: https://earthquakehub.xocta.com/privacy-policy/ Terms of Use: https://earthquakehub.xocta.com/terms/

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.
