Which SAT App Is Best for You?
No single app wins every category, and anyone who says otherwise is selling something. Pick by need:
Best Free Official Prep: Khan Academy + Bluebook
Khan Academy carries the official College Board lessons and question practice for free, and Bluebook carries the free full-length adaptive tests in the real test interface. Every student should use both regardless of what else they add.
Deepest Paid Explanations: UWorld
UWorld explains every answer choice on 1,700+ SAT-level questions, which is the fastest way to learn from mistakes if you are pushing for 1400+. Question bank access runs $99 for 30 days up to $249 for a year.
Best Paid Value: Magoosh
About $129 for a full year of self-paced prep with 1,750+ questions, 200+ video lessons, and a 100-point improvement guarantee. The middle ground between free official material and premium question banks.
Best Daily Practice Game: Larry Learns
The apps above are study tools; Larry Learns is the one built to make you show up every day. Streaks, duels, a live score estimate, and an explanation on every question, free for three quizzes a day, with the SAT and ACT in one account.

How This Comparison Works
Prices come from each vendor's own pricing page, checked August 26, 2026. Platform claims are checked against the App Store and Google Play. Where a vendor does not publish a number, we cite the third-party review we used or leave the cell blank rather than guess. Nobody pays for placement here, and Larry Learns is our own app, labeled as such, so you can weigh our take accordingly.

Larry Learns turns SAT prep into a daily game: short quizzes, streaks, duels, a live score estimate, and a step-by-step explanation on every one of its 25,000+ practice questions. The free tier gives you three quizzes and three explanations a day. One account works on iPhone, Android, and the web, and covers both the SAT and the ACT.
Strengths

- SAT and ACT in one account
- iPhone, Android, and web share one account
- Streaks and duels that keep you practicing
Trade-offs
- Questions are original, not official College Board items

Khan Academy Official SAT Prep
FreeBest for: Every student, as the official free foundation
Built in partnership with College Board, Khan Academy offers free lessons, videos, and practice questions across every Digital SAT skill at three difficulty levels. Full-length practice tests are no longer on Khan Academy itself: they moved to Bluebook, and Bluebook links you back to Khan for review. We wrote a full review of how to get the most from it.
Strengths
- Official College Board partnership, completely free
- Lessons and videos at three difficulty levels
- Linked from Bluebook for post-test review
Trade-offs
- Full-length tests moved to Bluebook
- No streaks or habit loop to keep you coming back
Bluebook (College Board)
FreeBest for: Everyone, for full-length official practice tests
Bluebook is the app you take the real Digital SAT in, and it offers free full-length adaptive practice tests with the real interface, timing, and built-in tools. It runs on Mac, Windows, and iPad rather than phones. Nothing else replicates the real test experience, so schedule your full-lengths here.
Strengths
- The real test interface, timing, and tools
- Free full-length adaptive practice tests
Trade-offs
- Does not run on phones
- Not built for daily practice between tests
UWorld SAT
QBank $99 (30 days) to $249 (a year); courses $299 to $449Best for: Students who learn from deep answer explanations
UWorld advertises 1,700+ SAT-level questions and explains every answer choice, not just the correct one, which is its signature strength. There is a 7-day free trial with 50 questions. It is a serious study tool rather than a habit app: expect a question bank and analytics, not streaks.
Strengths
- Every answer choice explained, right and wrong
- 1,700+ SAT-level questions with analytics
- 7-day free trial before paying
Trade-offs
- $99 to $449 depending on tier and duration
- A study tool, not a habit builder
Magoosh SAT
About $129 for 12 months self-pacedBest for: Budget-minded students who want video lessons plus a guarantee
Magoosh pairs 1,750+ practice questions with 200+ video lessons and a 100-point score improvement guarantee, per Test Prep Insight's 2026 review. It has iPhone and Android apps and a 7-day trial. It sits between free official material and premium question banks on both price and depth.
Strengths
- About $129 for a full year
- 200+ video lessons plus 1,750+ questions
- 100-point score improvement guarantee
Trade-offs
- Smaller question bank than UWorld
- Video-first pacing suits some learners, slows others
PrepScholar SAT
$397 for 12 months ($495 with AI assistant)Best for: Students who want a structured, adaptive program rather than an app
PrepScholar is a web-based program that diagnoses your level and assigns a weekly plan, backed by a 160-point score guarantee. There is no dedicated mobile prep app, so it suits students who study at a desk. A dual SAT plus ACT package is $597 if you are prepping for both.
Strengths
- Adaptive program that plans each week for you
- 160-point score improvement guarantee
Trade-offs
- $397/yr is the priciest self-paced option here
- Web-only, no mobile prep app

Also considered: Princeton Review and Kaplan, which are course-first products rather than practice apps; vocabulary-only apps, useful but covering one slice of one section; and the wave of AI apps that machine-generate their own questions. Whatever you pick, anchor your practice in a curated question bank or official material, because a generated question that grades you wrong teaches the wrong lesson.
SAT Prep by Platform
What Is the Best SAT Prep App for iPhone?
Khan Academy, UWorld, Magoosh, and Larry Learns all ship real iPhone apps; Bluebook does not run on phones, and PrepScholar is web-only. For turning bus rides and lunch breaks into practice, Larry Learns is built for the phone first: quizzes take a few minutes, streaks track daily habit, and your score estimate updates after every quiz.
What Is the Best SAT Prep App for Android?
The Android picture matches the iPhone one: Khan Academy, UWorld, Magoosh, and Larry Learns publish Google Play apps, while Bluebook and PrepScholar do not. Larry Learns landed on Google Play in 2026 with full parity: the same account, questions, streaks, and score tracking as iPhone and web. We break the Android setup down fully, including the Bluebook workaround, in our Android SAT prep guide.
Can You Prep for the SAT Online Without Downloading Anything?
Yes, and on a school Chromebook it is often your only option. Khan Academy, UWorld, Magoosh, PrepScholar, and Larry Learns all work fully in the browser. Larry Learns keeps web and app progress on one account, so a quiz finished on a school laptop counts toward the same streak as one on your phone. The exception is full-length official tests: those need the Bluebook application on a laptop or iPad.
What Is the Best Completely Free Way to Prep?
Stack three free layers: Khan Academy for official lessons, Bluebook for official full-length tests, and Larry Learns for daily question practice with streaks and explanations, free for three quizzes a day. That covers learning, realistic testing, and daily habit without spending anything.
How to Choose in Three Steps
- 1
Start free and official. Take a Bluebook full-length as a diagnostic, then work Khan Academy lessons on your weak areas. Not sure which test suits you? Read SAT vs ACT first.
- 2
Fix the habit problem. Most prep fails from inconsistency, not bad material. Add a daily-practice app with streaks so missing a day costs you something. This is the job Larry Learns is built for.
- 3
Pay only for a named gap. Chasing 1450+ and need deeper explanations? Trial UWorld. Want structured video lessons on a budget? Magoosh. Check your target with the score calculator before you spend.
Frequently Asked Questions About SAT Prep Apps
What is the best free SAT prep app?
Use two together: Khan Academy for official College Board lessons and question practice, and Bluebook for free full-length adaptive practice tests. For daily question practice on your phone with streaks and explanations, Larry Learns has a free tier with three quizzes a day, and it covers the ACT too.
What is the best SAT prep app for iPhone?
Khan Academy, UWorld, Magoosh, and Larry Learns all have real iPhone apps. Bluebook does not run on phones, so full-length official tests happen on a laptop or iPad. If you want phone practice that feels like a game instead of a textbook, Larry Learns is built around short daily quizzes with streaks and score tracking.
What is the best SAT prep app for Android?
Khan Academy, UWorld, Magoosh, and Larry Learns all publish Android apps on Google Play. Bluebook has no Android phone version, and PrepScholar is web-only. Larry Learns launched on Google Play in 2026 with the same account and progress as its iPhone and web versions.
Is Khan Academy enough to prep for the SAT?
For many students, yes: it is free, official, and thorough. Its weak spots are motivation and habit, since there is no streak or game loop pushing you to show up daily, and full-length tests now live in Bluebook. Many students pair official material with an app that makes daily practice a habit.
Are paid SAT prep apps worth it?
Only if you will actually use them. UWorld ($99 to $449) is known for the depth of its answer explanations, Magoosh ($129/yr) for affordable video lessons, and PrepScholar ($397/yr) for a structured program with a 160-point guarantee. Take the free trials first, and exhaust the free official material before paying.
Can I prep for the SAT without downloading an app?
Yes. Khan Academy, Magoosh, UWorld, PrepScholar, and Larry Learns all run in the browser, which matters on school Chromebooks where you cannot install apps. Larry Learns uses one account across web, iPhone, and Android, so practice started on a school laptop continues on your phone at home.
How many full-length practice tests should I take?
Most tutors suggest at least two to four full-length tests before test day: one early as a diagnostic and the rest spaced across your prep. Take official ones in Bluebook under real timing. Between full-lengths, short daily question practice builds the skills the tests measure.
