PrepScore SAT gives you a full practice system — thousands of original questions, full-length adaptive mock exams, spaced-repetition flashcards, and a practice-score estimate that updates as you work. WHAT YOU GET • Practice by domain — Reading & Writing and Math, every official domain and skill, with full explanations on every question. • Timed modules & full-length mocks — train against the real Digital SAT's module-adaptive format, with a built-in graphing calculator for Math. • Practice-score estimate — a 400–1600 estimate mapped from your accuracy, so you always know where you stand against your target. • A personalized day plan — sized to your goal and test date, it re-paces as you practice. • Mistake bank — everything you miss collects here to redo until you've got it. • Flashcards — index-card decks with spaced review on the moves the SAT actually tests. BUILT RIGHT Every question is written to the official SAT domain blueprint and independently checked before release. Your scores are practice estimates — not official SAT results. FREE & PRO Practice, your day plan, the score estimate and your mistake bank are free every day. Go Pro to remove daily caps: unlimited questions, flashcards, mocks, and every explanation. — SAT is a trademark registered by the College Board, which is not affiliated with, and does not endorse, this app. Practice scores are estimates and are not official SAT scores.

Verdict
The clearest difference is in-app purchases: Common App at none against SAT Prep's 3. Common App also leads on chart position (#28 vs unranked) and device support (3 vs 1). SAT Prep's advantage is update cadence (monthly vs every 9 months). On price and ads there is nothing between them.
