Help your Youth and Teens know WHY they believe โ€” not just what. The Why: Youth is a Christian apologetics app built for ages 9-18. Kids learn to ask honest questions about faith and find real, Bible-grounded answers. Teens step into roleplay conversations that prepare them for the doubts they'll meet in middle school, high school, and beyond. WHO IT'S FOR - Youth (ages 9-13): a friendly, story-driven introduction to the Bible, the Gospel, and the big "why" questions kids actually ask. - Teens (ages 14-18): deeper apologetics training, debate-style roleplay scenarios, and Gospel sharing prep. WHAT'S INSIDE CLASSES โ€” Short guided courses on the big questions. 26 classes, 146 lessons across kid and teen tracks. Each class is 4-6 short modules, each ~5 minutes of reading + a 3-question quick check, ending with an 8-question final test. Topics include Who is God? Who is Jesus? Is the Bible true? Other religions, science, hard things โ€” plus teen-only courses on Doubt & Deconstruction, Identity & Worth, Mental Health, Sexuality & Relationships, Culture & Relativism, Science & Big Questions, Digital Life, Suffering & Justice. ASK MODE โ€” A safe, kid-friendly Q&A space for honest faith questions: "Is the Bible true?", "Why does God let bad things happen?", "How do we know Jesus rose?" BIBLE DISCOVERY โ€” Bible stories, key heroes, places, and a guided timeline of redemption history. A Bible literacy course built for kids who don't know where to start. GOSPEL TRAINER โ€” Walk through the Gospel step-by-step and practice sharing it in your own words. Always free. PRACTICE MODE โ€” Multiple-choice and short-answer quizzes that build Bible knowledge and apologetics confidence. 200+ questions across People, Events, Books, Places, Parables, Kings, Prophets, the Lineage of Jesus, and How We Got the Bible. TEEN TRAINING โ€” Roleplay debate scenarios so teens practice the hard conversations before they matter. PARENT DASHBOARD โ€” See what your child is learning, what they're struggling with, and what they're proud of. Sensitive-topic classes are surfaced so parents can debrief. BUILT FOR FAMILIES - Multiple child profiles per parent account - Reformed and Evangelical content tracks - COPPA-compliant data handling for under-13 users - No ads, no third-party trackers serving kids - Parent-only settings area - Sign in once on the family parent account, manage every child PRICING (HONEST, NO TRICKS) - Gospel Trainer is ALWAYS free. Sharing the Gospel is not behind a paywall. - Ask Mode, Bible Discovery, and Classes are free starting points. - Plus subscription unlocks the full Practice library, Teen Training roleplay scenarios, and unlimited content. Optional. Affordable. Manage or cancel anytime in your store account. WHY THIS APP EXISTS Most kids never get a chance to ask the hard questions out loud. Most teens leave home for college without ever practicing a Gospel conversation. The Why: Kids is built so the next generation doesn't have to figure it out alone โ€” so kids learn the WHY behind the WHAT, and parents have a tool they can trust beside them. A Christian app for kids. A faith app for teens. A Bible quiz, a Gospel trainer, a Sunday school companion, and a parent's best ally for raising children who know what they believe and why. Made by a parent. Built for families. Anchored to Scripture. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
