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

How do you explain the Feast of the Epiphany to a six-year-old? How do you make Lent meaningful for your whole family? Sacra is more than a calendar. It is a guide for living the beauty of the church year together. A LIVING CALENDAR At the heart of Sacra is an interactive calendar wheel that guides you through all eight seasons: Advent, Christmas, Epiphany, Lent, Holy Week, Easter, Pentecost, and Ordinary Time. The colors, themes, and imagery shift with the seasons, helping your family feel the rhythm of the church year as it unfolds. FAMILY ACTIVITIES FOR EVERY SEASON Sacra includes activities for every season: crafts, devotionals, service projects, recipes, and more. Each one comes with step-by-step instructions, a materials list, age recommendations, and a Scripture connection. They are designed to help families experience the church year together in simple, meaningful ways. MORNING & EVENING PRAYER Each day offers a morning and evening prayer rooted in the themes of the current season. From the quiet hope of Advent to the bold joy of Easter, every prayer is thoughtfully written and paired with Scripture from the World English Bible. There are prayers here for every day of the year, written to draw you deeper into each season's meaning. THE REVISED COMMON LECTIONARY The complete three-year lectionary cycle is included, with Old Testament, Psalm, Epistle, and Gospel readings for every Sunday and major feast day. Full Scripture text is right in the app, so you can read and reflect without needing anything else. THE STORY BEHIND THE SEASONS Each season and feast day includes historical context, theological reflection, and notes on how different traditions observe it. These are not dry encyclopedia entries. They are written to help you understand and love the church year more deeply. YOUR TRADITION, HONORED During setup, you choose your tradition, and Sacra adapts. Anglican and Lutheran users see additional feast days. Terminology and Advent color options adjust to match your background. Throughout, Sacra follows the Revised Common Lectionary, the shared calendar of readings used across Protestant traditions, so the heart of the church year stays the same wherever you worship. DESIGNED FOR CONTEMPLATION The seasonal color palette, warm watercolor illustrations, and thoughtful typography are all designed to create a quiet, inviting space. This is an app meant to slow you down, not speed you up. WIDGETS FOR YOUR HOME SCREEN Stay connected to the church year from your home screen, lock screen, or StandBy mode. Widgets show the current season, a daily verse, and upcoming feast days. YOUR PRIVACY, RESPECTED Sacra makes zero network requests. There are no analytics, no tracking, no accounts, and no data collection of any kind. Everything runs entirely on your device. ACCESSIBILITY Sacra is a universal app for iPhone and iPad, with full VoiceOver support, Dynamic Type, Dark Mode, and Reduce Motion support. The iPad version includes sidebar navigation and full multitasking. ALSO INCLUDED - Apple Calendar export for the full church year - Search across prayers, activities, feast days, and readings - Favorites and activity completion tracking Sacra is a one-time purchase with no subscriptions, no in-app purchases, and no ads. Just a faithful companion for the Christian year, made with care.

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.
