Stuck on a stats problem at midnight? Snap a photo. Get a step-by-step explanation. Move on. An AI tutor built specifically for statistics and probability, not a generic math solver that happens to handle stats. Whether you're prepping for AP Statistics, taking your first probability theory class, or brushing up on hypothesis testing for work, this app meets you where the textbook left off. WHAT YOU CAN DO Snap & Solve: Take a photo of any stats or probability problem. The AI returns a clear, step-by-step solution. AI Tutor: Ask follow-up questions in plain language. The tutor remembers the problem context and explains until it clicks. Topic Library: Structured lessons covering descriptive statistics, probability, distributions (normal, binomial, Poisson), hypothesis testing, regression, Bayes theorem, and more. Practice Exercises: Work through hand-picked problems for each topic, with instant feedback. Topic Quizzes: A focused quiz at the end of every topic to lock in what you learned. Step-by-Step Explanations: No black-box answers. Every solution is broken down so you understand the why, not just the result. Built to Keep You Going: Daily streaks, level progress, and small wins to keep practice habits sticking. WHO IT'S FOR - High school students taking AP Statistics or first-year stats - College undergrads in intro stats, business stats, or probability theory - Grad students brushing up before exams - Working professionals (data analysts, A/B testers, MBAs) who need a quick refresher - Anyone who has Googled "what does p-value mean" more than twice WHY STATS-FOCUSED MATTERS Generic math solvers handle stats as an afterthought. They'll give you the answer to a binomial probability question, but they won't explain why you used a binomial distribution in the first place. This app was built from the ground up for statistical reasoning, so the explanations actually teach you the subject, not just the calculation. PRIVACY Works without an account. We don't ask for your name, email, or any identifying info during normal use. Photos you scan are sent to the AI to generate an answer and then deleted, never stored on our servers. Full privacy policy in Settings. Questions or feature requests? Tap Settings, then Feature Request inside the app. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
