Frequently asked questions
What is the best completely free math app?
Khan Academy Kids is the best 100% free option—no ads, no paywalls, no subscriptions. For older kids (grades 1-8), Prodigy offers all educational content free, and Zearn provides a complete K-8 curriculum at no cost.
Is Prodigy really free?
Yes, Prodigy's educational content is completely free—all 50,000+ math questions covering grades 1-8 are available without paying. The premium membership ($59-180/year) only unlocks extra game features like pets and rewards, not educational content.
Are free math apps as good as paid ones?
Often, yes! Khan Academy Kids and Zearn are nonprofit-backed and offer high-quality, research-backed content. Prodigy's free tier covers all academic content. Paid apps like DreamBox may offer deeper adaptive instruction, but free options can be just as effective for practice.
What free math apps work offline?
Most free math apps require internet. Khan Academy Kids allows some offline use after initial download. For fully offline math, consider one-time purchase apps like DragonBox ($7.99-$24.99) which work without internet.
Which free app is best for kindergarten math?
Khan Academy Kids is ideal for kindergarten—it's 100% free, covers counting, shapes, patterns, and basic addition/subtraction. Starfall also offers much of its early math content for free.
Our Verdict
Best 100% free: Khan Academy Kids offers complete early learning (ages 2-8) with absolutely no cost or ads—it's genuinely free.
Best for grades 1-8: Prodigy makes all 50,000+ math questions free. Zearn offers a complete standards-aligned curriculum at no cost.
Best for homework help: Photomath's free version solves problems via camera with step-by-step explanations.
Note: Free apps with ads (like Turtle Diary, ABCya) work fine but require parental supervision. Ad-free options like Khan Academy Kids are preferable for younger children.
