Digital SAT® verbal exam prep
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
13,000+ original Reading & Writing questions, clear explanations for every choice, adaptive review, and an optional on-device tutor on supported devices.
PRACTICE WITH PURPOSE
Build SAT® Reading and Writing skills with 13,000+ original practice questions across all four domains. Every answer includes a detailed explanation of why the correct choice works and why the other choices do not.
LEARN FROM EVERY ANSWER
• See clear explanations for correct and incorrect choices.
• Review the clue, the tested skill, and the reasoning behind the answer.
• On supported devices, ask the optional on-device tutor for another explanation or strategy.
PRACTICE AT MODULE PACE
Choose a quick check, a standard practice set, or a full 27-question module with a 32-minute limit. The timer continues if you leave the app, and a review-and-flag screen lets you check your work before submitting.
ALL FOUR SAT® READING AND WRITING DOMAINS
• Craft and Structure: Words in Context, Text Structure and Purpose, Cross-Text Connections
• Information and Ideas: Central Ideas and Details, Command of Evidence, Inferences
• Expression of Ideas: Transitions, Rhetorical Synthesis
• Standard English Conventions: Boundaries, Form, Structure, and Sense
LEARN AND REVIEW
• Study 2,500+ vocabulary words with definitions, examples, word parts, and related terms.
• Tap words in passages for definitions and pronunciation.
• Use adaptive drills and spaced review based on your answers.
• Follow your coverage, patterns, and suggested next steps in the Learning Map.
PRIVATE BY DESIGN
Core questions and learning content are included with the app. No account is required, there are no ads, and study activity is not sent to us. The optional tutor uses Apple Foundation Models and runs on-device on supported models with Apple Intelligence enabled.
FREE AND PLUS
Practice free each day with a daily adaptive drill and spaced review. Every new installation receives seven days of full access without starting a subscription or payment authorization. After the free-access week, Plus unlocks unlimited Drills, full timed Tests, and every Learn pack.
