Snoaf is the bedtime app you don't have to manage. Your child picks a story or lullaby, it plays, and then it stops — no ads, no account, and nothing about your child collected, stored, or shared. Most kids' apps are built to keep a child watching. Snoaf is built the other way: each story is short, each story ends, and nothing queues up another one on its own. No endless feed, no algorithm picking what your child sees next. Download a story once — over Wi-Fi or data — and it plays completely offline forever after, even in airplane mode. No sign-in, ever, for downloading or for anything else in the app. THREE CALM WAYS TO SHARE A STORY • Listen — sit back and let it read aloud, page turns and all • Listen with the screen off — close your eyes; the story keeps playing in the dark • Read together — a picture book with a soft illustration on every page, and a text box you can move out of the art's way YOUR VOICE AT BEDTIME Record a short goodnight message that plays after the story ends — or record a whole story in your own voice, or a grandparent's, and it joins the shelf like any other. Recordings stay on the device; they're never uploaded or shared. ON THE TELEVISION Send the picture book to a TV over AirPlay or HDMI and the phone becomes the remote — the story on the big screen, the controls in your hand. It works entirely offline, like everything else here. FOR MORE THAN ONE CHILD Add each child, pick who's listening tonight, and keep separate favourites. Line up a few stories as a playlist for the nights you already know how it goes. FIVE NIGHT WORLDS Choose the sky behind the stories — midnight, fireflies, snowfall, campfire, or rain. Each one is its own quiet, drifting world, not a colour swap. INSIDE THE LIBRARY Three stories, seven lullabies, and every ambient sleep sound — rain, ocean, wind, white noise — are yours free, right out of the box. The Family Unlock, one simple one-time purchase, opens the whole library: 21 original stories across 47 short episodes, every lullaby (instrumental or gently sung), and every story we add next, at no extra charge. Tap any sealed story to hear a little peek of the real narration before you decide. Download only the stories you want; remove any of them later to free up space, any time. BUILT FOR SMALL HANDS AND TIRED PARENTS • Child lock — once a story starts, little fingers can't skip, exit, or wander off; unlocking takes a grown-up • A parental gate keeps recording, settings, and anything to do with purchases out of reach • A sleep timer fades everything out on its own • Slow the narration down (or gently speed it up) to match your child's pace • Start tonight's story from a Home Screen, Lock Screen, or StandBy widget — or just ask Siri MADE FOR CALM, MADE FOR TRUST • No ads. No third-party trackers. Nothing about your child is collected — the App Store privacy label reads Data Not Collected. • No account, no login, no sign-up, ever. Free to start — three stories, lullabies, and sleep sounds included. One optional one-time Family Unlock opens everything, forever. Never a subscription. Meet Snoaf — a sleepy little marshmallow who reads one story, then says goodnight.
