Best SAT prep apps in 2026: free and paid
The best SAT prep apps are free and official. Bluebook, the College Board app you take the test in, has full-length practice tests. Khan Academy gives free lessons and a study plan. For more drills, add the free College Board question bank, or pay for UWorld. StudyPDF turns your own class notes into practice. Prices are as of October 2026.
Start with the free official tools. The digital SAT runs in College Board's Bluebook app: two sections, Reading and Writing and Math, each split into two adaptive modules, about 2 hours 14 minutes in total, with a Desmos calculator built in. Practice in Bluebook and nothing on test day will surprise you.
A free plan that works for most students: take one Bluebook practice test, work on your weakest skills with Khan Academy and the Student Question Bank, then retest every two to three weeks. Pay for something like UWorld only when you run out of official questions or want more explanation. Our guide at studypdf.net/answers/how-to-study-for-the-sat has a week-by-week plan.
Taking the ACT instead? ACT links free practice tests from act.org, and students who register with a fee waiver get The Official ACT Self-Paced Course, powered by Kaplan, at no cost. StudyPDF also has free 15-question samplers for the ACT at studypdf.net/quizzes/act-practice-questions and the PSAT at studypdf.net/quizzes/psat-practice-test. Our team wrote them; they are not official items.

Strengths
- The real test screen, timer and built-in Desmos calculator
- Score reports point to the skills you miss
Limits
- No lessons: it shows what you missed, not how to fix it
- No phone app, and a limited number of tests, so use them as checkpoints

Strengths

- Official free tools come first because they match the test best and cost nothing.
- Prices come from each vendor's own site, checked October 2026. Prices change, so check before you pay.
