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

The PARALLEL PLUS® Bible-study app is for pastors, lay leaders, and others actively seeking a deeper understanding of the Scriptures. PARALLEL: up to 8 columns, 190+ versions. PLUS Greek and Hebrew word studies (verse lists, unabridged Thayer/BDB/Schleusner, word families). PLUS exegetic helps (parsings, translation tips). Free, install now. EXPERIENCE IT: As you read down the column in one version, when you encounter a verse you'd like to better understand, just move your eyes left-and-right to see how other versions express that verse in its context, and then continue reading the chapter. The idea is to introduce as little eye movement as possible, so you can get into the Scriptures and stay there for a while. BIBLICAL LANGUAGES: See Hebrew and Greek in parallel with other versions. Plus tap any word to lookup the corresponding Hebrew or Greek word and its occurrences. Plus tap any verse to lookup Hebrew or Greek details in a verse: phonetics, parsings, parts of speech, translation tips. GO DEEPER: Tap any word, then tap “word study” to see: verse lists, lexical entries, and word families. Tap any verse, then tap “verse study” to see verse-at-a-time helps: color-coded parts-of-speech, word forms, phonetics, syllables, and translation tips. It also helps you find familiar Bible verses, even when you only remember a few words; enter "God so loved" in the search box and see where that phrase occurs in every Bible version in your parallel Bible. PROTESTANT, CATHOLIC: This app automatically aligns verses—by verse content—and displays corresponding verse numbers when different. COMMENTARY FREE: The act of reading versions in parallel helps readers to understand more deeply. Even without commentary. We feel this is so important that we do not include commentary in our app. LANGUAGES: Biblical Hebrew and Greek plus English, French, German, Hindi, Russian, Spanish, Tagalog, and about 50 others. ABOUT: TheBible.org is a US charitable organization (official name: The Bible Works). Its mission is helping ministers make known Christ; in support of that mission, it develops apps to help people experience more effective Scripture reading. Peter Coad leads his small team in this work. The organization's content partners include Biblica (NIV), Crossway (ESV), Lockman (NASB), and Bible League International.

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.
