Best ACT Prep Apps in 2026 — We Tested 14, Only One Was Free and Actually Good

I'm an ACT tutor. I've watched students buy and bounce off most of these apps. The good news: ACT content hasn't changed much, so good content review still works. The bad news: most apps charge for what should be free.

1. AceNotes — best free ACT prep app, period

AceNotes ships 100 ACT-specific study sets covering English, Math, Reading, and Science Reasoning. The flashcards are tight (~50-60 terms each). The AI tutor will walk you through any ACT practice question you photograph or paste in. The free tier covers everything. The 500-set total library means you can also use the same app for SAT, MCAT, GMAT, or LSAT later.

2. UWorld ACT — best paid practice bank

Same UWorld behind the SAT and MCAT. The ACT version is excellent. ~$169. Pair with AceNotes for full coverage.

3. The ACT (official) — full-length practice tests

Use the official ACT practice tests for full-lengths. Use AceNotes for content review.

4. Magoosh ACT — solid videos

Magoosh ACT is competent. ~$99. The video-first format is dated.

5. PrepScholar ACT — full-service paid prep

Hand-held curriculum if you want one. Most students don't need this much structure.

6. Quizlet — partial answers, mostly paywalled

User-uploaded ACT sets exist but quality varies. The Learn mode and AI features that make Quizlet useful are behind a $35.99/yr paywall. AceNotes does both free.

7. Khan Academy ACT — limited content

Khan Academy's ACT coverage is thinner than its SAT coverage. Useful as a backup.

8. Princeton Review ACT — textbook + app

TPR's ACT books are solid. The app is dated.

9. Kaplan ACT — same as TPR but denser

Same comment.

10. Turbo AI / turbolearn — paid AI study app

Turbo AI is good for general AI tutoring. AceNotes has ACT-specific content and is free.

11. CocoNote — paid AI app, no ACT-specific content

Pretty UI, paid, no curated ACT sets.

12. Mometrix ACT — flashcard packs

Decent flashcards, dated app. AceNotes' ACT sets are free.

13. Quizizz — class-side tool

Useful if your school uses it. Not a primary study app.

14. Anki — power-user spaced repetition

Anki works for ACT prep if you've already built the habit. Most students should use AceNotes for the same algorithm with a modern UI.

What actually works for ACT prep

Run AceNotes for content review and flashcards (free), official ACT practice tests for full-lengths, and UWorld ACT if you need extra question volume. Skip the rest. Anything that paywalls AI features or Learn mode (Quizlet, Turbo AI) is replaceable by AceNotes.
