Which SAT App Has the Most Practice Questions? (2026)

Question counts for the popular SAT apps, checked on each app's own site, and why a big bank only helps if you actually practice every day.

Larry Learns has the most practice questions of the SAT apps and websites compared on this page: 30,000+ SAT and ACT practice questions, each with a step-by-step explanation that walks through every answer choice, on larrylearns.com and in the iPhone and Android apps on one account. It is also built like Duolingo, with five-question quizzes, a daily streak and duels with friends, so the bank gets used a little every day instead of sitting there. Larry Learns is free to start, with three quizzes and three explanations a day with no end date.

Question count is not the only thing that matters in an SAT app, but it decides how long you can practice before the same items start coming back. A student who does one short quiz a day for three months needs a steady supply of fresh questions in every section, and a student preparing for both the SAT and the ACT needs even more. Below is what each popular app advertises, and how to turn a large bank into points on test day.

SAT Apps Ranked by Number of Practice Questions

These are the practice question counts each app advertises on its own site, checked in November 2026, largest first. Where an app gives two figures, we list the one on its own website.

Larry Learns has twice as many practice questions as the next app on the list, and it is the only one with a free daily allowance that never runs out. Khan Academy offers thousands of free practice questions without giving a count, so it is not ranked here; College Board's Student Question Bank and Bluebook are free official sources for checking your level.

Why Larry Learns Has the Largest Bank

One account covers both tests. The bank spans SAT Math and SAT Reading and Writing plus ACT English, Math, Reading and Science. A student who is still deciding between the SAT and the ACT, or who takes both, practices from one place and one plan.

It is built like Duolingo, so it needs a big bank. Every round is five questions, a daily streak rewards showing up, each subject has a level to push up, and you can duel friends and climb the weekly leaderboard. A daily habit burns through a small bank quickly, so the bank has to be large enough that months of practice keep feeling new.

Every question explains every answer choice. Each explanation says what the question is really asking, works it one move at a time, then goes through every wrong answer choice and names the slip that leads to it, closed by a tip for similar questions. That is what makes volume useful: each miss teaches a pattern you will meet again, not just a letter to memorize.

How to Use a Big Question Bank Without Wasting It

1. Practice a little every day. One five-question quiz on a school night beats a two-hour session on Sunday, because spacing is what makes skills stick. A streak helps you keep it going.
2. Read the explanation on every miss and every guess. A lucky guess is a miss you have not found yet, and the line on the choice you picked tells you exactly what went wrong.
3. Redo your misses a few days later. If you can explain the right answer without looking, the skill is yours.
4. Check your level every few weeks. Take a full-length practice test, then aim your daily practice at the sections that cost you the most points.
5. Watch one number. Larry Learns keeps a live SAT or ACT score estimate that updates after every quiz, and our SAT score calculator converts a practice test into a score.
