Bedtime doesn't have to be a battle. A gentle Bible story tonight. The whole Bible when they're ready. Free, offline, no ads. FireFly turns Scripture into a calm nightly ritual: a narrated story, a prayer, and lights out. Then, as your child grows and the questions get bigger, the complete Bible is already waiting in the same app. No account. No subscription. No second download. THE WHOLE BIBLE, BUNDLED AND OFFLINE All 66 books of the World English Bible live right inside FireFly. Search the entire text, bookmark chapters you love, and tap Continue Reading to return to your place. It works on a plane, in the car, or anywhere with no signal, because the whole Bible is stored on the device rather than streamed. The wording matches the verses quoted in the stories, so a child can go straight from tonight's story to the passage it came from. This is the Bible your family grows into. BIBLE STORIES, FULLY NARRATED A growing library of narrated stories, and each one is a faithful retelling of a real passage, with its own illustration, a memory verse to learn by heart, a bedtime prayer, and a Talk About It question for the two of you. Warm AI narration reads every word aloud while read-along highlighting follows the text. ONE STORY, WHICHEVER CHILD IS LISTENING Every story is written three times over: Little Stars (ages 2-4), Bright Stars (4-8), and Shooting Stars (8+). Pick the level for each child, so siblings can share the same story and each hear it their own way. A PICTURE BOOK THAT TURNS ITS OWN PAGES Open any story in Storybook Mode: a full-screen picture book with a full painted illustration on every page, turning itself in time with the narration, so a child who cannot read yet can still follow along. HEAR THE SCRIPTURE ITSELF Behind every story is the full Bible passage it came from, read aloud by that story's narrator. Tap Scripture and listen to the real words. YOUR VOICE, ON THE NIGHTS YOU'RE AWAY With Parent Voice, a grown-up records a story into the app while a teleprompter scrolls the script. That recording becomes what your child hears at bedtime. Recordings never leave your device. MADE FOR EYES THAT ARE ALREADY CLOSING Narration keeps playing with the screen locked, with lock-screen controls. Lights Out darkens the whole screen while the story plays, and Kid Lock keeps little fingers from waking it. A sleep timer fades the story out, Sleepy Speed slows the reading down, and six ambient sounds carry your child the rest of the way. Turn on Wind-Down and the app dims itself into bedtime mode when bedtime arrives. A SIMPLE ROUTINE Story, then prayer, then goodnight. That is the whole thing. GENTLE BIBLE GAMES Story Quiz, Who Am I?, True or False, Guess the Story, Badge and Treasure Match, Story Scramble, Verse Builder, Verse Practice, and the Inspiration Tree, where children grow an A to Z tree of words about Jesus. No trick questions, and every ending is encouraging. REWARDS WORTH KEEPING Reading streaks, badges, story treasures to collect, and Lumi's Night Sky, where your child decorates a sky of their own with stickers and the treasures they have earned, then saves it to Photos. FOR THE WHOLE FAMILY Up to four child profiles, each with their own streaks, favorites, and collection, synced privately through your own iCloud. You can even ask Siri to play tonight's story. FREE MEANS FREE No ads. No in-app purchases. No paywall. No subscription. No "unlock the rest." No sign-up, no email address, no accounts of any kind. No tracking and no data collection. COPPA-compliant by design, with a parental gate on anything meant for grown-ups. Nothing your family does leaves your devices and your own iCloud, unless a parent chooses to turn on optional AI voices with their own key. Scripture is the public-domain World English Bible. Lumi the firefly is waiting. Good night, and sleep well.
