WonderMath puts you in charge of your child's math practice. You choose the operations, set the number ranges, and decide what your child works on. No algorithm makes that decision. You do. Your child practices in a colorful, encouraging environment with Bob the Frog, a studious, glasses-wearing math tutor who celebrates correct answers, encourages them through tough problems, and patiently walks them through mistakes step by step. HOW IT WORKS 1. Sign in with Apple and create a profile for your child 2. Pick from 21 skill-based templates or build a custom test from scratch 3. Hand the device to your child and let Bob take it from here 4. Review results, track mastery, and see exactly where they need help WHAT MAKES WONDERMATH DIFFERENT - You choose the math: Addition, subtraction, multiplication, division, or any combination. Set exact number ranges for focused practice that matches your child's level. - 21 pre-built templates: Addition Sums to 10, Times Tables through 12, Mixed Operations, Math Facts Sprint, and more. Organized by skill and difficulty so you can start in seconds. - Bob the Frog: Your child's personal math tutor. Bob cheers for correct answers, encourages them when they struggle, and guides through mistakes with patience, not pressure. - Smart hints, not handouts: Progressive hints steer your child toward the answer without giving it away. Hints reduce the score, encouraging children to try first and ask for help second. - Retry before reveal: Wrong answers get a second chance. If they still need help, Bob explains the solution step by step. - Real mastery tracking: Mastery scores weight recent practice and first-try answers, so you can see which operations are strong and which need work. Every test is saved in your child's history, so you can look back over time. - Trophy system: Gold (90%+), Silver (75%+), and Bronze (60%+) trophies reward effort and accuracy. - Optional parent PIN: Set a PIN if you want your child to stay in a test until you're back to check their work, or leave it off so they can exit on their own terms. Change it anytime in Settings. - Works with your curriculum: Built to complement Common Core, Abeka, Saxon, Singapore Math, Classical Conversations, Math-U-See, Teaching Textbooks, and Horizons. - Syncs across devices: Your family's data stays in sync across all your Apple devices through iCloud.

About

Tutor Kay

Read full description

Tutor Kay (just "Kay" to her students) is an AI math tutor built by Ms. K, a former California high school math teacher. Kay teaches the way a real human tutor does — patient, encouraging, and never giving you the answer before you've tried. WHAT KAY DOES - Walks you through any math problem step-by-step, with hints instead of solutions - Explains concepts from counting through topology in plain English - Takes you through full SAT Math practice tests with real exam timing (22 questions, 35 minutes) - Shows your accuracy by topic so you know exactly where to focus - Renders math properly (LaTeX), draws diagrams, and even reads questions aloud - Accepts photos of your handwritten work — show Kay what you tried BUILT FOR REAL STUDENTS Kay is free. There's no signup wall. There are no ads. There's no email harvesting. Just open the app and start learning. If you want your progress to sync across devices, you can set up a passkey account — your data is tied to a random nickname like "purple-tiger-7421," never to your real identity. 5 FULL SAT MATH PRACTICE TESTS Each test mirrors the real Module 1 mix: Algebra, Advanced Math, Problem-Solving & Data Analysis, and Geometry & Trigonometry. Diagrams are embedded right in the question. The timer matches Bluebook. Your score breaks down by domain so you know exactly what to study next. WHO BUILT THIS Tutor Kay was built by Radhika Kolachina, a former CA math teacher who wanted every student to have access to a patient, encouraging tutor — not just the ones who could afford one. Kay is the AI tutor she wished her own students had. PRIVACY Kay doesn't ask for your name, your email, or anything else to use her. Chat messages aren't stored on Kay's servers — only in your own browser. Read the full privacy policy at tutorkay.ai/privacy. Questions, feedback, or just want to say hi? Tap "Send feedback" inside the app. Ms. K reads every message. — K
