The mark experiment
Read full descriptionHide full description
Have you ever tried to memorize a part of the Bible, e.g. a complete book? The gospel of Mark has a very intelligent structure that is very easy to memorize. It is the set of headlines like they are printed above a section in the Bible. This structure is basis for e.g. the Mark theatre, where 15 actors play the complete gospel in 90 minutes in a theatre-in-the-round without any stage props. This is very impressive. Anyway, memorizing the gospel is a very good idea for studying the Bible without the physical book. This app is meant to be a training to people who already learned the structure (partially) anyway, as a smartphone is much quicker in use than a non-interactive piece of paper. It is based on the book published by VTR Publications. The app can walk trough three different levels of the structure: The complete gospel, one of the six parts (or the introduction or conclusion) or a midsection. For every step, four possible answers are shown to select the correct one. Afterwards, an emoji rates the quality and quantity of your recitation. To get a good rating, you need be fast without thinking about all choices.

Bible apps have become social platforms, full of feeds and features that distract you from simply reading the Bible. Cardinal is different. Just you, God and Scripture. No noise. Read Cardinal opens on the Majority Standard Bible, plain modern English. Thirteen translations are free and always will be; eight read fully offline, including the King James, World English and Berean Standard. Reading Scripture never requires a subscription. Long-press and drag to highlight exactly the words you chose, not the whole verse. Save favorites and write in the margins. Listen Hear Scripture read aloud, the words lighting up in time and the page following on its own. Six narrators, a sleep timer, adjustable pace, AirPlay, and it keeps playing on the lock screen. Ask Read a passage and think, "What does that actually mean?" Ask, and get an answer drawn from the verse in front of you: cross-references, word studies, context. Thirty of the biggest questions about Christianity are answered in full, free, plus three of your own each month. Beyond that, Ask is Cardinal Pro. More Translations The NKJV, NASB, CSB and NLT come with Cardinal Pro, each with a free day to try. Read two side by side and see where they differ. Their licenses do not allow storing the text, so these four always need a connection. Quiet Time: Your Daily Time Set Apart One guided sitting a day. Pause, read, reflect, apply, pray, close. Each day is fifteen to twenty-five verses, a whole scene rather than a chapter. After seven in the evening a shorter sitting appears. Your archive is searchable and private, and what you pray for goes to a list you can mark answered. Nine curated paths, from the Story of Jesus in John to the whole Bible in a year. Or describe what you are facing and Cardinal builds a path around it, free, with every day shown before you begin. No streaks. No badges. No missed-day guilt. Just time set apart. Scripture Memorization Practice two ways: first-letter hints, or hidden words, which blanks more of the verse each pass until you can say it from the reference. Verses you are still learning come back sooner, under "Ready to come back" rather than a streak you broke. Notes: For Sermons You Hear and Sermons You Give A sermon note is for when someone else preaches. It opens with Scripture and notes; big idea, main points with their verses, Living It Out and action steps get added when you want them. Group them by series. Studies is for when you are the one teaching (Cardinal Pro). Name a passage, say what it is about, and Cardinal offers the cross-references, places, key verses and original-language words it holds, each with a line on why it belongs. It finds them on your phone from bundled data, so it cannot cite what it cannot point at, and nothing is added until you tick it. It gathers; it never writes your message. Podium mode is what you preach from: read-only, lectern-sized type, every passage loaded before you stand up. Editing a study needs Pro; reading, exporting as Markdown and preaching from one never do. Threads: Someone Has Been Where You Are Twenty-four lives of Scripture, found by what they are about, not by name: fear, grief, shame, waiting. Each told as the few moments that made it, plotted across the whole Bible. A hundred and forty moments, free. Journeys: Walk Where It Happened Paul's voyages, Abraham's road, the Exodus and Passion Week, flown place to place over 3D satellite maps. Each stop tells what happened there, reads aloud, and shares as a card. Seventeen journeys, free for everyone. Widgets and Watch Pin a Verse of the Day, today's Quiet Time passage, or Memorize progress. The Apple Watch app works with no phone near. Works Offline Memorize, study, highlight and take notes anywhere. Only audio, Ask and the four licensed translations need a connection. Why Cardinal? Cardinal is for people who want to read Scripture, sit with it, and talk to God. That's it. Terms of Use: https://cardinalbible.app/terms-of-use.html

Verdict
The clearest difference is in-app purchases: The mark experiment at none against Cardinal Bible's 2. The mark experiment also leads on iOS requirement (9.2 vs 17.0). Cardinal Bible's advantage is update cadence (every 2 days vs every 31 months). On price, ads and device support there is nothing between them.
