Thankfully, with the technology that’s available today, quality test prep doesn’t have to be only for those who can afford it. Read on to get our list of the best apps for FREE ACT and SAT exam prep!

What are the best apps for free SAT and ACT prep?


  1. Best for Memorization: Magoosh ACT and SAT Flashcards
  2. ACT Flashcards: Apple Store / Google Play
    SAT Flashcards: Apple Store / Google Play

    Yeah, these are ours, so we are a little biased, but really, we think they’re great :).

    ACT Flashcards from Magoosh were designed by experts on the test and updated for the latest content on the ACT. They cover the essential English, math, and science knowledge students need to know and are a confidence-boosting supplement to practice questions. Our SAT Vocabulary and Prep Flashcards are similarly designed to cover SAT vocabulary words, writing, and math concepts that you need to succeed on the exam.

    The apps are built with a smart algorithm that adapts to you; once terms are mastered they are removed from the pool so you can focus on the concepts you still need to learn. Your progress is synced across devices so you can switch between phone, iPad, and web for convenient studying wherever you are.

  3. Best for Overall ACT and SAT Prep: Khan Academy
  4. Apple Store / Google Play

    Khan Academy’s slogan is free, world-class education for anyone, anywhere, and this makes it one of the best companies out there for no-cost learning. The Khan Academy’s official partnership with the College Board for the redesigned SAT means that it has significantly expanded its resources for SAT prep. However, the best use of the Khan Academy app for ACT and SAT prep is the general math video lessons covering all of the topics on these tests. So whether you need to brush up on ratios, complex numbers, or coordinate geometry, a quick video lesson on the Khan Academy app may be all you need to set you on the right path.

    Note: Since College Board’s study app, Daily Practice app, is no longer supported, College Board recommends students use the Khan Academy app for comprehensive, free exam preparation.

  5. Best for SAT Writing/ACT English Prep: The Grading Game
  6. Apple Store

    The Grading Game initially might seem like an oddball selection for ACT and SAT prep, but the format of the game—which invites players to hunt down a wide range of errors within sample essays—is a great match for the format of the new SAT Writing and ACT English sections, which asks students to do the same thing. You can practice at a range of difficulty levels, and the ticking clock helps train your brain to find grammar, sentence structure, and style errors quickly and effectively.

  7. Best for ACT and SAT Math Prep: Math Brain Booster
  8. Apple Store

    The no-calculator section on the SAT makes mental math an even more essential skill for the high-scoring student to master, but this app helps students with both ACT and SAT prep. Math Brain Booster improves your attention span, reaction time, and mental sharpness by challenging you to solve different arithmetical tasks within a time limit. It’s fun, streamlined, and very effective as a free exam preparation app.
