A Bible you can keep.
11Thy word have I hid in mine heart, that I might not sin against thee.
Eleven complete translations, every word offline, and a memorisation drill built to make verses stay. No account. No feed. Nothing added to the text.
Free. iPhone and iPad. Nothing about the Bible itself is ever locked.
Free, for good
The whole Bible. Not a sample of it.
Every translation is downloaded with the app. It works on a plane, in a basement, on a hike — forever.
The whole text, eleven times over
King James, Webster, Berean Standard, World English, Majority Standard, American Standard, Young's Literal, Darby, Geneva 1599, Douay-Rheims, and the Bible in Basic English.
Real study tools
194,290 cross-references, Strong's Hebrew and Greek behind every King James word, full-text search, and one verse across all eleven translations at once.
Your own margins
Highlights in five colours, notes on any verse, kept verses, a prayer list — backed up to your own private iCloud, readable by nobody else, including us.
Read
Set like a page, not a settings screen.
Warm paper, a proper serif, the words of Christ in red, paragraphs where the printed Bible has them. Your typeface, size, spacing and margins — or turn the verse numbers off and read a chapter as prose.
- Listen with the screen locked, with lock-screen and CarPlay controls
- Reading plans — five built in, or make your own
- A verse each morning: on your home screen, your lock screen, or Siri
Memorise
Learn it until it's yours.
Five stages — read it, fill light gaps, heavy gaps, first letters only, then the whole verse from nothing. Spaced repetition brings each verse back exactly when you are about to lose it.
- Every correct word has weight — haptics nobody else in the category uses
- Say it aloud and have it checked word by word, on your phone, never sent anywhere
- Streaks for reading and for remembering, counted separately
Compare
Scripture illuminating Scripture.
One verse, eleven committees. Where they differ is where the original is hardest to carry into English — and By Heart shows you the difference and says nothing about it.
Games
Six games, built from the text itself.
Missing word. Where's it from? What comes next? Which translation? Finish the verse. Chapter and verse. They get harder as you play — and only as fast as you can keep up.
- Three free rounds a day
- Ads only here, never beside Scripture

6Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
JOHN 14:6 · KJV · THE WORDS OF CHRIST IN RED, AS PRINTED SINCE 1899
What you read is what the translators wrote. Every translation is public domain or freely licensed, and the text was checked word for word against an independent source before it shipped — 2,038 red-letter passages included, Christ's words and only Christ's words.
There is no commentary, no study notes, no AI-written explanation, and no interpretation of any kind anywhere in By Heart. Where translations differ, it shows you the difference and says nothing about it. People who read the Bible take it seriously. So does this.
iPhone and iPad
Every size, the same page.
A single readable column that respects your system text size, from the smallest iPhone to the 13-inch iPad, in every orientation.
