Why?!
Read full descriptionHide full description
Why?! is the safe digital knowledge companion for children aged 4 to 16. With a lovingly animated animal character as their guide, your children can ask all their questions – anything that comes to mind. The app grows with your child and automatically adapts answers to their respective age. The App That Grows With Your Child From preschool to adolescence, Why?! accompanies your children on their journey of discovery. Younger ones can simply ask their questions by voice – even if they can't read yet. As soon as your child starts learning to read, text is additionally displayed. For older children from about 10 years old, the app offers a complete chat interface as a safe alternative to uncontrolled AI tools. This way, your children get exactly the support they need at their respective developmental stage. Playful Learning With the Bottles & Glasses System Children learn not only knowledge, but also conscious resource management. Each week they receive a "knowledge bottle" that they can distribute over seven days. This makes the abstract use of AI tangible and playfully teaches that resources are valuable. A lovingly animated fox accompanies every interaction and makes learning a joyful experience. Does the learning companion become a friend? No. Why?! transparently teaches children that it's an AI – a learning tool without feelings. This honesty promotes a healthy relationship with technology. Real friendships are formed with people. Perfectly Designed for Families You can create up to five child profiles and make individual settings for each child. The app shows you which topics particularly interest your children – without seeing the conversations themselves. You get valuable insights and conversation starters while your children's privacy remains protected. This relieves you from the many "Why?" questions of daily life while giving you the assurance that your children are safely interacting with AI. Security You Can Rely On Full control remains with you: You decide which of the 15 topic areas may be discussed. The adult area is PIN-protected, so only you can change the settings. This way you can be sure that your children are learning in a protected environment. Privacy is not an option for Why?!, but a standard. We minimize data storage to the essentials, use European servers, and comply with COPPA and GDPR guidelines for children’s applications. Flexible Subscriptions for Every Family Test Why?! in the first month at a heavily discounted price and then decide which subscription fits your family. The monthly or annual subscriptions are tiered by number of children – from one to five children. Why?! turns childhood curiosity into a safe learning experience – developed by parents for parents.

CurioKids is an AI-powered learning buddy designed for kids ages 5–13. Just type — or say — a question about words, math, science, history, or anything curious, and get a clear, age-appropriate answer in seconds. In English, Spanish, or Simplified Chinese. No clutter, no distractions. Just learning. Certified with a 5-star rating by the Educational App Store. QUADSHIELD SAFETY Built around one idea: so simple a 5-year-old can use it, so safe you don't have to watch over their shoulder. Every question passes through four independent safety layers before your child sees a response: a keyword filter blocks inappropriate topics instantly, an AI classifier screens every question for age-appropriateness, age-tuned AI instructions ensure answers match your child's level, and images are individually screened before they're shown. All filters work in every supported language. No tracking, no ads, no data shared. Unlike general-purpose AI chatbots, CurioKids is purpose-built for young learners. ONE APP, ENDLESS LEARNING CurioKids replaces a whole shelf of learning tools. It's a dictionary that explains words in context, an encyclopedia that makes any topic approachable, and four subject tutors — Math, Reading, Science, and History — that guide your child step by step. Instead of juggling multiple apps, your child has one friendly place to ask anything and actually understand the answer. WHAT KIDS CAN DO • Ask about anything — words, math, science, animals, space, and more • Ask by typing or talking — CurioKids answers in the language of the question • Switch to Math, Reading, Science, or History Tutor for guided practice • Go on Adventures — step-by-step journeys through space, dinosaurs, or any topic they dream up • Tap highlighted tricky words for a kid-friendly meaning • Hear any answer read aloud • Build a "Words I Learned" collection and practice it with a fun word quiz • Earn 37 achievement badges and level up from Curious Beginner to Ultimate Genius (25 levels) • Complete daily tasks and answer the Question of the Day for bonus XP • Track streaks and view a weekly learning recap • Share what you've learned as beautiful branded cards • Take a photo and ask "what is this?"

A new Question of the Day appears every morning. Weekly recaps celebrate progress. And 37 badges — from Curious Cat to Monthly Master — give kids something to aim for. It's the fun of a game with the substance of a tutor.
