Marble vs Unknown app

Marble is an interactive world that turns your kid's curiosity into learning. And it never feels like school. They explore worlds, take on quests, make things, solve problems and follow their questions wherever they lead: dinosaurs, space, drawing, music, storms, machines. Marble listens and adapts, so every adventure is built around what your kid cares about. (WHAT YOUR KID GETS) - A living world that grows with their interests and adapts to their level. No passive feed to scroll. - Quests where they build, create, and figure things out - A guide that never runs out of patience for the 677th "why?" question - Challenges that teach them to get stuck, try again, and win (WHAT YOU GET) - A daily note on what they explored and what they're learning - One connected map of their curiosity( skills, interests, breakthroughs) based on the US and UK curriculum standards - Ideas for real-world activities to keep the spark going off-screen - Valuable, active screen time. No passive mindless watching. (BUILT FOR CHILDHOOD) - Designed for kids ages 6–12 - No ads. No algorithmic feed. - COPPA compliant: parents create every account, we don't sell data, and you can review or delete your kid's information anytime - Made by parents who believe technology should be worthy of childhood (BETA) We're building Marble with our community. Join us to give us feedback and help us make Marble great for kids around the world. Questions? Ideas? Your kid would want to ride a whale to reach the next island?

Unknown turns dense reading into listening. Add a PDF, EPUB or paper and Unknown narrates it in a lifelike voice, lighting up every line on the real pages as it plays. YOUR OWN VOICE Read a few short passages aloud and Unknown narrates any document in your voice. Try it free for 5 minutes. Unknown Pro includes 1 free hour, and you can add 3, 6 or 12 more hours as one-time purchases. Your recordings stay on your device and go to our cloud only with documents narrated there, and are deleted as soon as each is ready. NO MAC NEEDED Add documents right on your iPhone or iPad: upload a file, paste a link, or share one from any app. Without a Mac, Unknown converts them in the cloud, up to 30 documents and 2,000 pages a month, 500 pages per document. With the Unknown app for Mac, documents are narrated privately on your Mac with no limits and appear here automatically. READ ALONG ON THE REAL PAGES The actual pages render on screen while the current paragraph lights up in sync with the audio. Swipe to a page and the audio follows. YOUR WHOLE LIBRARY, IN SYNC Progress, bookmarks, notes and mind maps sync through your account between your iPhone, iPad and Mac. Pause on the Mac, resume on your iPhone. FIND PAPERS ON ARXIV Search arXiv from the app and listen to any paper. MIND MAPS Maps generated on your Mac arrive with each document: the whole argument at a glance. WIDGETS AND SHORTCUTS Pick up where you left off from a Home Screen widget or a Control Center control. PRIVACY Documents your Mac narrates sync through your own iCloud, and no server of ours sees them. Documents converted in the cloud are sent over an encrypted connection, deleted after 7 days, never read by a person and never used to train AI. Voice recordings sent along for narration are deleted as soon as the document is ready. BUILT FOR LISTENING Background audio with lock screen controls, adjustable speed, 15 second skips, and paragraph by paragraph highlighting. SUBSCRIPTION Your first 2 documents are free, and a sample document is included. Unknown Pro unlocks the whole app with a weekly, monthly or yearly subscription; monthly and yearly start with a 7-day free trial for new subscribers. Payment is charged to your Apple ID when you confirm the purchase, or when the free trial ends. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your App Store account settings. Unknown Pro also works in the Mac app and on unknown.ac. Voice hours for narrating in your own voice are one-time purchases that need an active subscription to use.
