Building a complete routine without buying a course
Free SAT prep app guide
Best Free SAT Prep Apps
Build your plan around ongoing free resources, not a collection of expiring trials. Keep a place for lessons, questions, mistake review, and official full-length practice.
Quick answer
Which SAT prep apps and resources are actually free?
College Board provides free official Bluebook tests and the Student Question Bank; Khan Academy provides free Digital SAT course instruction. Dolphin SAT is free on iPhone and Android for short daily practice with explanations. These are different tools, not four interchangeable test apps. You do not need to buy a course just to access official digital practice tests.

What can you use without a paid SAT course?
Published by Dolphin SAT. This source-based guide checks ongoing free access, the learning task each resource covers, and the gaps a student must fill elsewhere. A free download or short trial does not establish that every feature is free. This is not an independent score-gain ranking; check current access terms before entering payment details.
| Resource | Free access | What it does not replace |
|---|---|---|
| BluebookOfficial practice features | Official scored digital practice tests at no charge. | Skill instruction between tests. It needs a supported device and does not run on a phone. |
| Khan AcademyFree official course | Official SAT lessons, examples, and leveled practice are free. | Official full-length digital testing in Bluebook. Use the SAT web courses for skill learning. |
| Student Question BankQuestion bank guide | Free official questions with filters for targeted skill practice. | A ready-made schedule or timed test. Choose a skill and review why each answer works. |
| Dolphin SATApp listing | Free iOS starting point with question practice and explanations. | Official Bluebook testing. Do not assume the separate web offering or every future feature is included in free mobile access. |
A look at Dolphin SAT
How can you prepare without paying for a course?
Step 1
What belongs in a free SAT study routine?
Start with your Bluebook answer review in My Practice: identify a missed or uncertain question and name the skill behind it. Choose a relevant Khan Academy lesson and difficulty level, then filter the Student Question Bank by that skill for a short practice set. Write the error, correction, and next review in a notebook. Try fresh questions without notes before moving on; if the same error returns, revisit the lesson. This is a student-directed way to personalize free preparation, not a claim that Bluebook scores automatically sync to Khan Academy. Dolphin can add short phone sessions between study blocks.
Step 2
How do you spot a trial instead of ongoing free access?
Check whether practice stops after a set number of days, whether explanations are locked, and whether a payment method starts a renewing subscription. A free download alone answers none of those questions. The official resources in this list provide free SAT practice or instruction; optional services and separate products can have different terms.
Step 3
Do you have to pay for full-length SAT practice tests?
No. Official scored digital practice tests are available free in Bluebook. Budget for the time and supported device, not a required test-prep subscription. Paid services may add instruction or convenience, but do not upgrade solely because you think official full-length practice is behind a paywall.
Step 4
How do you know when free resources are not enough?
Look for an unresolved problem: you cannot explain a concept after studying it, repeat the same reasoning error, or struggle to follow any plan. Ask a teacher or counselor about available help before assuming a purchase is necessary. Consider paid instruction only when you can describe what extra support you need and verify that the service provides it.

FAQ
Is a free SAT prep app enough to study with?
Free resources can cover lessons, targeted questions, and full-length practice. A phone app alone is not the same as that complete routine; combine it with official testing and deliberate review.
Are official Bluebook practice tests free?
Yes. College Board provides scored full-length digital practice tests in Bluebook without a paid test-prep subscription. Use a supported device; phones cannot run Bluebook.
Does Dolphin SAT cost money?
Dolphin SAT is free to start on iOS. That does not mean every web feature or separate offering is free; review the current terms of the product you choose.
Can you personalize SAT study without paying for an app?
Yes. Use your official test review to choose a weak skill, study a free lesson, and test the correction with fresh questions. Adjust your next session based on the error you still make. You can keep that plan in a notebook without buying automated recommendations.
