Live mobile study workflow
Keep passages, notes, references, and sources in one study workspace.

Current mobile release
Real Flutter screens from the current build, centered around the study surfaces that already ship today.
Map workspaceWord studyOffline library
Letters
Wesley, Whitefield, Athanasius, Chrysostom, and the Apostolic Fathers, each enriched with scripture refs and topic chips.
Greek & Hebrew
Tap any word in the reader to see its lexicon entry, top renderings, and every place it occurs in the canon.
Scroll timeline
Walk the product one screen at a time.
This section turns the shipped mobile surfaces into a scroll-driven sequence: each step highlights a real capture and explains what that screen contributes to the study workflow.
Step 01
Tap any word in the reader to open its Greek or Hebrew lexicon.
Tap "Word" on John 1:1 and the reader pulls up λόγος (G3056) with its full definition, top renderings ring chart, and every place it occurs in the canon. The lexicon sheet slides over the verse without losing your reading position.
339 verses where λόγος occurs, jumpable from the panel
- Word / Verse toggle — switch between lexical entry and whole-verse breakdown.
- Definition, transliteration, Strong’s number, and a ring chart of top renderings.
Step 02
Open the native hymn-score player on any installed hymnal.
The hymn player renders the actual score with an amber beat-cursor that walks through every measure, with stacked verse lyrics and per-verse audio across vocal, piano, and organ.
3 voices vocal, piano, organ — generated per hymn
- Beat-aligned cursor on real sheet music, no WebView.
- Hymnal catalog organized by tradition and meter.
Step 03
Read theologian letters with scripture refs and topic chips above the text.
Letter collections from Wesley, Whitefield, the Apostolic Fathers, Calvin, and Rutherford ship enriched: every letter carries its scripture references and topic tags right above the body text.
49 refs in a single Clement of Rome letter
- Patristic, Reformed, Anglican, and Methodist authors in one catalog.
- Refs and topics generated by an LLM-assisted ingestion pipeline.
Step 04
Expand any note into a per-verse reference workspace.
Tap a passage note to open its Reference view: a labeled diagram of connected verses, plus Topic Network, Notes, and Open Passage tabs and a Connected / Statistics breakdown for the link set.
5 links around John 3:14-17 with parallel + allusion + symbol labels
- Reference, Topic Network, Notes, and Open Passage tabs on one surface.
- Add a reference inline without leaving the passage view.
Step 05
Flip to Statistics to see which topics the passage actually concentrates on.
The Statistics tab inside any note charts Topics by Reference on a radar — tap Parallel, Allusion, or Symbol/Object to filter the chart. Bar counts beneath the radar show the link distribution at a glance.
3 / 1 / 1 Parallel / Allusion / Symbol-Object links on John 3:14-17
- Topics radar with axes for Love, Justification, Messiah, Repentance, Atonement, Grace, TULIP, Prayer, Resurrection.
- Per-link-type filter chips toggle which references feed the chart.
Step 06
Pull every kind of source for the verse into one swipeable Sources panel.
Select a verse — say John 1:1 — and the Sources sheet opens with six tabs: Commentaries, Confessions, Reference, Note, Hymns, and Letters. Matthew Henry’s commentary on John 1 sits a single swipe away from the Westminster confessions, a Reformed hymn on the Word, or a letter that quotes the passage.
6 tabs Commentaries · Confessions · Reference · Note · Hymns · Letters
- Sources panel groups results by tradition (Puritans, Reformed, Patristic, …).
- Swipe through installed cards inside the same sheet — never leave the verse.

Primary flows
The site is built around the six product surfaces the app already ships.
The marketing copy mirrors the actual route structure and screen responsibilities in the Flutter client. Bible, Read, Hymns, Letters, the per-note Reference workspace, and Library are the six first-class surfaces you can land on every day.
Bible
Reading built for verse interaction and Greek/Hebrew word study
The Bible reader supports translation switching, book and chapter navigation, verse targeting, and a Strong’s-backed Greek and Hebrew lexicon panel that opens beside the text.
- Jump directly by translation, book, chapter, and verse.
- Tap any underlined word to see its lexicon entry, top renderings, and occurrence count.
- Open commentary and confession context from the scripture surface.
Read
Resume active study sessions without rebuilding context
Read mode brings together continue-reading state, active passages, top topics, quick actions, and passage search in one dashboard.
- Return to the exact translation and reading location you left.
- Move into Topics, Library, Export, or Bible from the same surface.
- Keep active passages and notes close instead of scattering them.
Hymns
A native synced-score player for the historic hymnal
Browse hymnals by tradition, then open any hymn into a native score view that scrolls the amber cursor through the staff while audio plays. Renders offline, no WebView.
- Hymnal catalog organized by tradition and meter.
- Beat-aligned cursor over the actual sheet music, with stacked verse lyrics.
- Per-verse audio across vocal, piano, and organ — generated from the score.
Letters
Theologian letters with refs and topics chips inline
Download letter collections from Wesley, Whitefield, the Apostolic Fathers, Calvin, Rutherford, Athanasius, Chrysostom, and more. Each letter ships with scripture refs and topic tags surfaced above the text.
- Patristic, Reformed, Anglican, and Methodist authors in one catalog.
- Scripture references and topic chips above every letter, generated by an LLM-assisted pipeline.
- Offline reading once installed — no network needed to study a letter.
Notes · Reference view
Every note opens into its own reference workspace
Tap any passage note to expand a per-verse view: connected references shown as a labeled diagram, Topic Network, Notes, and Open Passage tabs, plus a Connected / Statistics breakdown of every link.
- Reference diagram with Parallel, Allusion, and Symbol/Object labels around the target verse.
- Switch between Reference, Topic Network, Notes, and Open Passage from the same surface.
- Add a reference inline — no separate editor screen needed.
Library
Remote catalogs with local installs and offline access
Library mode separates what is installed on the device from what is available remotely across commentary, hymn, letter, and confession collections.
- Install commentary voices, hymnals, and letter collections for offline reading.
- Browse confessions, creeds, and theological standards by tradition.
- Keep bookmarks and recent sections available inside the reader.
Research stack
The surrounding tools turn the reader into a full study environment.
Beyond reading and mapping, Exegesis already includes the library, theological sources, topic management, export surface, and account access needed to support serious recurring use.
Greek & Hebrew lexicon
Tap any underlined word in the reader to see its Strong’s entry, top renderings, KJV usage, and full occurrence list across the canon.

Rollout
Mobile and Desktop are closer to shipping.
Mobile already carries the serious core of Bible reading, mapping, hymns, letters, library, and analytics.
