Read full description

Master the Math section of the fully digital, adaptive SAT — the version that actually shows up in Bluebook today. Digital SAT Math Mastery is built around the two-module adaptive format and the on-screen Desmos calculator, not repackaged paper-test material. Everything in the app points at one goal: walking into test day ready to score. A COMPLETE PRACTICE ENGINE • Full-length Mock Exams — 44 questions across two timed modules (70 minutes), just like the real thing. Get an instant pass/fail against the 70% line, then review every question with a worked explanation. • Practice by Topic — untimed drills for any chapter with immediate, clear feedback. • 200+ practice questions with step-by-step solutions, spanning Algebra, Advanced Math, Problem-Solving & Data Analysis, and Geometry & Trigonometry. KNOW YOUR WEAK SPOTS • Exam History charts your score over time so you can watch it climb. • Weak-topic analysis pinpoints exactly which topics are costing you points — so every study session counts. • A Readiness score blends your quizzes, mock exams, reading, and flashcards into one honest number. LEARN AND REMEMBER • 124 spaced-repetition flashcards lock in the formulas, definitions, and key facts you need. • Per-chapter quizzes with instant feedback and explanations. • A searchable Cheat Sheet of formulas and key points, plus a full glossary. TOOLS THAT BUILD DISCIPLINE • Study Planner — set your exam date and daily goal, and get a day-by-day plan you can check off. • Study Timer — a Pomodoro focus timer that feeds your streak and progress. • Exam-day Countdown and a Study Streak to keep you moving every day. • 12 achievements that unlock as you improve. THE COMPLETE GUIDE, INCLUDED The full 12-chapter guide is built right in as an offline bonus — covering the new digital format, Bluebook navigation, mastering the Desmos calculator, all four math domains, pacing and the adaptive scoring strategy, smart guessing, common mistakes, and a complete test-day game plan. Adjustable text size, bookmarks, and resume-where-you-left-off. PRIVATE AND OFFLINE BY DESIGN • Works completely offline — study anywhere, no connection needed. • No account, no sign-up, no ads, and no in-app purchases. • Your progress stays on your device. We don't collect your data. Built for iPhone and iPad. Set your exam date, follow your plan, mine your mistakes, and let the adaptive test work in your favor.
