Think Math vs Blitz

Think Math is a concept explorer that lays out every math concept from elementary through high school on a single map. 802 concepts cover the whole curriculum, from counting to calculus. Narrow things down in three steps - area, unit, concept - to find what you need fast. Fractions, roots, exponents and sigma notation are typeset properly, just like a textbook. Concepts are linked to short YouTube concept videos, so you can read an idea and then watch it. KEY FEATURES * 802 concepts across elementary, middle and high school * Three-step navigation: area > unit > concept * Textbook-quality math typesetting (fractions, roots, exponents, sigma) * 700+ English concept videos, linked concept by concept (more added over time) * Explanations and examples written at each grade's level * Concept cards with Basic and Advanced views * Listen and learn: hear any concept read aloud * Wrong-Answer Notes (save photos, handwriting and formulas) * Summit hall - enrichment math beyond the curriculum * Study streaks and daily reminders * In English and Korean - switch any time from the home screen * Layouts for iPhone and iPad (iPad works in portrait and landscape) GREAT FOR * Students who want to see how units connect in the big picture * Test-takers who want a fast concept review * Parents who want to see how math builds grade by grade * Teachers who need a concept map for class * Math lovers who enjoy thinking through proofs and formulas PRIVACY AND USE * No sign-up needed - just open and start. * All study data stays on your device and is never sent to a server. * Ads are shown to keep the app free (Google AdMob). An optional one-time Pro purchase removes ads. * On first launch, iOS asks whether to allow tracking. You can decline and still use every feature.
