Kaira: Math — gentle math practice for ages 7–9 Meet Kaira, a friendly Samoyed who keeps your child company during math practice. Kaira: Math is a calm, ad-free arithmetic app built on what cognitive science actually says about how kids learn math — not on points, streaks, or pressure. A DIFFERENT KIND OF MATH APP Most kids' math apps use coins, scores, and leaderboards to keep children engaged. Research on child motivation shows these rewards can actually reduce a child's interest in learning over time. Kaira: Math takes a different path. Children progress by building real skill, one step at a time, with Kaira by their side. HOW IT WORKS Your child chooses a skill to practice and how many problems to solve: 5, 10, or 15. Each skill has two phases: - Learning mode — calm, untimed, with gentle hints when something feels hard. Mistakes are treated as information, not failures. - Fluency mode — unlocks only after your child is consistently accurate. A playful way to build speed once the foundation is solid. New skills unlock automatically as earlier ones are mastered. No skill is ever forced, no skill is ever skipped. WHAT YOUR CHILD PRACTICES 25 carefully sequenced addition and subtraction skills, from single-digit facts through three-digit problems with carrying and borrowing. The progression is built on evidence-based strategies like "making tens" and decomposition — the same techniques great teachers use. THE PARENT DASHBOARD Behind a PIN, parents get a dashboard that shows what really matters: which skills your child is working on, where they are stuck, and what kind of mistakes they are making. Not just "73% correct" but "most errors are forgotten carries" — with specific suggestions for how to help at home. PRIVATE BY DESIGN - All data stays on your device. No accounts, no cloud, no sign-up. - No ads. Ever. - No analytics or tracking of your child. - No network connection required to use the app. FOR AGES 7–9 Designed for children in roughly 2nd through 4th grade who are working on double-digit addition, subtraction, carrying, and borrowing. Kaira: Math is not a replacement for school math — it is a calm, private place to build fluency and confidence between lessons. SUBSCRIPTION Kaira: Math Premium unlocks full access to all skills and the parent dashboard. Try it free for 7 days, then $4.99/month or $29.99/year. Cancel anytime in your Apple ID settings.

Parenyx is a parenting app for parents of children ages 3–12—from preschool on up—that suggests daily activities to do with your child. Ten minutes in the evening instead of battling over the phone: each activity is tailored to your child’s specific age, interests, and personality. You choose a developmental goal—focus, kindness, discipline, responsibility, courage, and more—and Parenyx turns it into short daily tasks, including simple chores. You complete them together, build a streak of days with a built-in chores tracker, and watch as small steps add up to a real habit. The app stays in your hands: your child doesn’t need yet another gadget. Key features: • A daily activity: a personalized 10-minute plan, not a generic checklist—tailored to your child’s age, interests, and chosen goal. • 10 character-building goals: focus, kindness, discipline, responsibility, courage, and more. Each goal includes a resource-backed breakdown for parents. • Mira, a 24/7 AI parenting coach: tantrums, screen time, arguments with siblings, school anxiety, motivation. Calm advice tailored to your specific situation, not just a blog post. • A hero who grows alongside your child: Each goal has its own character, who levels up as tasks are completed. The activities feel like a game. • Progress and reports: A series of days, 50 levels for each goal, and a monthly report that’s easy to understand. • A personalized certificate for completing all available tasks: tangible proof of the progress made. • Up to 10 child profiles: Each child has their own plan, goals, and progress. • Reminders at convenient times: A user-friendly notification system. • Offline access: Saved assignments can be opened without an internet connection—on the go, at the cottage, or while traveling. • Four interface languages: Russian, English, German, and Spanish. Why choose Parenyx? • Practicality over theory: instead of “developing perseverance,” get a ready-made assignment for tonight. • Screen time-friendly: a parenting app for parents—your child gets your attention, not just another screen. • Manageable for busy parents: 10 minutes a day, no preparation required, and no need to buy materials. • For the whole family: a separate plan for each child, tailored to their age and personality. • Free and Premium: start with demo assignments, then try full access for 3 days free.
