Verse Loop Daily

Start the day by memorizing ESV verses word-by-word — from first letters, with the reference tested last.

A native iOS app (SwiftUI, zero dependencies, offline-first) built for one workflow: a single due-sorted Loop, one verse at a time, with real spaced repetition behind it. One daily Loop, one tester, one scheduler.

How a rep feels

The reference stays hidden and no word counts are shown. Type the first letter of each word, one at a time — then, without breaking stride, the reference: book initial, then numbers (the colon is skipped). tlimsisnwp231 flows in as one session while the reference composes inline as Psalm 23:1, styled just like the words. Multi-verse passages work too (Psalm 23:1-6 ends …p2316, separators appearing on their own).

Right character → it appears. Wrong → a haptic buzz, a red mistake, and you move on. Every mistake carries its own "accidental?" toggle — tap any red word to forgive a fat-finger slip (shaking forgives the latest too). The header shows a mistake count, net of forgiven slips, instead of a progress bar. Then you see your mistakes plus a suggested grade, and you grade Again / Hard / Good / Easy. Grades get an 8-second Undo. Full dark-mode support throughout.

What you get

• Single due-sorted Loop: one verse at a time
• Wrong letter buzzes + marks a red mistake — forgive any as accidental
• Every rep ends in Again / Hard / Good / Easy → real SM-2 ease + intervals
• Mistake count in the header, net of forgiven slips, plus a suggested grade
• JSON export/import + optional encrypted sync — same verses on two devices

Getting it

The app is distributed via TestFlight for iPhone (iOS 17+, iPhone SE 3 supported). Install Apple's TestFlight app, accept the invite, and you're in — the two built-in demo verses work with zero setup.

To add real verses, just type a reference like John 1:1 or Psalm 23:1-6. ESV text is fetched automatically through the app's built-in service; nothing to configure on-device.

Your verses are yours

• Works offline. Reviews are pure on-device computation; one network call per verse add, cached forever locally.
• Backup however you like. Export/import your library as JSON from Settings, or use the optional sync as encrypted backup. Sync is end-to-end encrypted — the server only ever sees ciphertext it can't read.
• Tiny and private. No web views, no media, no analytics SDKs. Cold start to an interactive Loop in under a second; the app bundle is ~1.4 MB.

ESV, legally

The app is ESV-only. ESV text is © Crossway and is never bundled in this repo or the app download — the two demo verses are public-domain KJV so the app works offline out of the box. Real ESV passages arrive at runtime via the ESV API, with the key held server-side.

Scripture quotations are from the ESV® Bible (The Holy Bible, English Standard Version®), © 2001 by Crossway, a publishing ministry of Good News Publishers. Used by permission via the ESV API. All rights reserved.

How releases work

Pushing to main is all it takes:

• App → TestFlight via Xcode Cloud, which builds the iPhone app and ships it to testers.
• Server via a GitHub Action that redeploys the small Cloudflare Worker (ESV proxy + encrypted sync store) automatically.

For developers and agents

See AGENTS.md for project layout, how to run the simulator and UI tests, and the guardrails (no ESV text in git, zero dependencies, opaque sync, SE3 target).
