The best test prep apps help you study smarter for the SAT, ACT, LSAT, MCAT, TEAS, GRE, and GMAT: with practice questions, timed tests, and adaptive learning on your phone.
The right app depends on which test you’re taking, how far out your test date is, and whether you need free resources or a premium structured plan.
Here’s a complete breakdown of the top options by test.
Best SAT prep apps
The best SAT prep app is Khan Academy’s Official SAT Practice, which is free and officially partnered with the College Board. It adapts to your skill level, builds personalized practice sets, and includes full-length timed practice tests modeled on the current digital SAT format.

For students who want more depth, UWorld SAT provides detailed answer explanations that teach you the reasoning behind each question, not just the correct answer. It also has a score predictor that tracks your likely score based on recent performance. PrepScholar is the strongest adaptive option, automatically identifying your weakest skill areas and directing practice there.
Best LSAT study apps
The LSAT is among the hardest standardized tests to self-prepare for because its logic games and analytical reasoning sections require a very specific trained approach. Generic study apps don’t work well here. The best LSAT study apps are built around teaching that approach from scratch.
7Sage is consistently the top-rated LSAT platform. It includes over 9,000 real LSAT questions with video explanations for every single one, a logic games analyzer, and a full analytics dashboard. Plans start around $99 for 3 months. For a lower-cost option, Magoosh LSAT offers 200+ video lessons and a clean mobile experience at around $149 for 6 months.
ℹ️ Note: The LSAC (Law School Admission Council) licenses real LSAT questions through its LawHub platform. Any serious LSAT prep app incorporates official LSAC material. Verify this before subscribing to any service.
Best MCAT study apps
The MCAT covers four sections across roughly 7.5 hours. The best MCAT study apps cover all four sections: Biological and Biochemical Foundations, Chemical and Physical Foundations, Psychological/Social Foundations, and Critical Analysis and Reasoning.
The AAMC’s official resources at the AAMC website are the most accurate predictor of real performance. Official full-length practice tests are the gold standard for MCAT prep and should be saved for the final 4 to 6 weeks before test day.
For daily practice, UWorld MCAT and Blueprint MCAT lead the category. UWorld has the strongest question explanations. Blueprint’s algorithm continuously re-surfaces content you got wrong, which accelerates long-term retention. Both run approximately $99 to $299 per month for full access.
Best TEAS prep app
The TEAS (Test of Essential Academic Skills) is required for most nursing program admissions and covers reading, math, science, and English. The best TEAS prep app comes from ATI itself: ATI TEAS Smart Prep uses real TEAS-style questions and mirrors the actual exam format closely.
Pocket Prep TEAS is the strongest third-party mobile app for the TEAS, with 900+ practice questions and detailed explanations. It runs around $13 per month and works well as a daily 15-minute supplement to the official ATI material.
Best MCAT prep apps vs. LSAT apps: key differences
These two tests require very different prep strategies, and that shapes which app features matter most.
Best ACT prep app
ACT Academy is the official free app from ACT Inc. and the best starting point for ACT prep. It covers English, Math, Reading, and Science with practice questions aligned to your score goal and includes full-length practice tests.
For more structured instruction, Magoosh ACT (~$30/month) and Princeton Review offer video lessons that explain concept by concept in addition to practice questions. Both are a strong step up from the official free resources if you’re targeting a significant score improvement.
Best GMAT prep app
The GMAT Focus Edition (the current version) tests quantitative reasoning, verbal reasoning, and data insights. The GMAT prep app most recommended by test-takers is the official GMAT Official Prep app from GMAC, which includes two free full-length practice exams and hundreds of real past GMAT questions.
For quant-heavy practice, Target Test Prep is the highest-rated paid option. Most GMAT score improvements come from strengthening quant performance, and TTP’s course focuses exactly there. Plans run around $99 to $199 per month.
How to build a test prep routine that works
Apps are most effective as a daily practice habit, not an occasional cramming session. Here’s how to structure your prep regardless of which test you’re taking.
Best GRE prep apps
The GRE (Graduate Record Examination) is required by most graduate school programs and tests verbal reasoning, quantitative reasoning, and analytical writing. The best official resource is the ETS PowerPrep app, which provides two free full-length practice tests that mirror the real exam’s format and scoring exactly.
For more structured prep, Magoosh GRE (~$149 for 6 months) offers 200+ video lessons and 1,000+ practice questions with detailed explanations. Manhattan Prep GRE is stronger on the verbal side, particularly for vocabulary and argument analysis questions that many test-takers underestimate.
Pick the app that matches your specific test from the options above. Start with the free resources to establish a baseline score, then decide whether a paid subscription is worth the cost based on how far you need to improve.
