Every parent gets the same recommendation from someone: just download a math app. The problem is that most lists lump together math apps that are completely free, apps that lock the useful parts behind a subscription, and apps that are more cereal-box toy than teaching tool. The digital age gave families hundreds of free math apps to pick from, and the gap between the best and worst of them is bigger than the gap between most paid ones. Below is a parent-view sort of apps and games that actually help kids build math skills at home, with concrete ideas for which one to recommend to your own child, grouped by what they need: a daily habit, homework help, or a first touch with numbers.
Quick answer: Khan Academy and Khan Academy Kids are completely free with no ads or paywalls. MathHero is free for five levels per day, which is enough for a focused 10 to 15 minute daily session. Photomath and Microsoft Math Solver are free for scanning problems and getting step-by-step solutions. Prodigy Math and Todo Math are free with optional paid tiers. DragonBox apps are paid but genuinely teach algebra concepts to young children.
What "free" actually means in a math app
The word "free" in the app stores covers at least four different things. There are tools funded by nonprofits (Khan Academy) that stay entirely free forever. There are freemium apps that give you a usable slice and sell the rest. There are AI-powered solvers that are free to scan a math problem but charge for the full explanations. And there are games that call themselves free but gate so much content behind a paywall that kids hit it by day two.
Before you download anything, it's worth a 60-second check on the app's listing page: whether in-app purchases are listed, what the recent reviews say about paywalls, and whether the free version actually covers your child's grade. That small habit saves a lot of "Dad, it won't let me play" moments later in the week and helps you avoid downloading three apps for the job one can do.
Seven free math apps worth your child's screen time
1. Khan Academy Kids and Khan Academy
Ages: 2 to 8 (Kids), 8 and up (main app) Platforms: iOS, Android, web
Khan Academy is the gold standard for truly free. The nonprofit model means no ads, no paywalls, and no upgrade-to-unlock screens. Khan Academy Kids offers free math content for children ages 2 to 8, covering early numbers, counting, shapes, and simple addition through animated characters and short stories. The main Khan Academy app picks up from there and covers content from basic arithmetic to advanced calculus, with short videos followed by practice problems your child has to solve to move on. The app shows progress on each skill in a clear tree view and gives immediate feedback on mistakes.
What makes it work for daily study: the mastery path keeps a child on the next right skill rather than letting them drift. What it won't do: Khan Academy is lesson-driven. It teaches concepts first, then asks kids to solve. Kids who already dislike math often find the pace slow and the practice sets dry, and the real challenge for most families is getting the child to open the app on their own.
Price: Free forever, no in-app purchases.
2. MathHero
Ages: 5 to 10 (K to 4th grade) Platforms: iOS, Android
If your child groans at a math worksheet, MathHero takes the opposite approach. It's a full story-driven adventure game where solving addition, subtraction, times tables, and division is how you play. Children rescue animals, earn coins, customize their hero's outfit, and move the story forward by solving short sets of math problems. The parent chooses the topic, the difficulty, the answer format (typed or multiple choice), and even the monster speed, so one child profile can fit a cautious first-grader while the sibling profile fits a fast fourth-grader on the same device.
The free version includes the whole game, not a demo. No content is locked. The only limit is pace: five levels per day per child profile, which works out to a focused 10 to 15 minute session. For most families, that's exactly the amount of daily math practice a child under 10 will do without pushback, and short regular practice is how arithmetic fluency actually builds. A subscription with a free trial removes the daily cap for kids who want to binge the story. There are no ads at any tier, which matters when kids are opening the app unsupervised.
Honest limits: MathHero does not teach counting from scratch or cover fractions, geometry, or video lessons. It starts at a child's first addition problems within 10 and ends at multiplication, division, and arithmetic up to 1,000.
Store ratings (US, Oct 2026): Google Play 4.6 (46k reviews), App Store 4.7 (11k reviews). Price: Free with five levels per day; subscription with free trial available (check in-app for current pricing).
3. Photomath
Ages: 10 and up Platforms: iOS, Android
Photomath lives in the homework-help category and is the app most middle-schoolers reach for when they can't solve math problems on their own. Your child points the phone at a math problem (printed, handwritten, or on a screen), the AI recognizes it, and Photomath breaks problems into easy-to-understand steps a middle-schooler can follow, from basic algebra to trig. Used as a check after your child has tried to solve the problem, it works like a patient tutor who never gets tired. Used before trying, it short-circuits actual learning and turns into an answer key.
The honest trade-off: this tool enables copying homework if a child is left with it alone. House rule worth setting at home: try to solve the problem first, use Photomath as the tutor to understand where you went wrong second. If math homework has become a nightly fight at your table, this parent guide to helping with math homework walks through the habits that make an app like Photomath actually useful instead of a shortcut.
Price: Free for basic step solutions; Photomath Plus subscription unlocks animated explanations and textbook solutions (check current pricing in the app).
4. Prodigy Math
Ages: 6 to 14 (grades 1 to 8) Platforms: iOS, Android, web
Prodigy Math uses game mechanics to teach math skills across the elementary and middle-school curriculum. Children build an avatar, battle monsters, and progress through a wizard-themed world by solving grade-aligned math problems between fights. Parents get email reports on what their child practiced each week, which shows you the topics they're avoiding.
The honest reality: Prodigy is free, but the game includes frequent prompts to upgrade to a Premium Membership that unlocks member-only pets, outfits, and areas. If your child gets frustrated at seeing locked content, that can become its own challenge, and some kids find the constant upgrade nudges a bigger challenge than the math itself. If they can ignore the upsells, the free game delivers real practice.
Price: Free with optional Premium Membership (check current pricing on the website).
5. Microsoft Math Solver
Ages: 10 and up Platforms: iOS, Android, web
Microsoft Math Solver is the quiet, no-ads alternative to Photomath, and one of the few math tools in this list that's completely free with no premium tier at all. It handles typed, handwritten, and scanned problems, uses AI to solve a wide range of math problems, and provides step-by-step explanations for arithmetic, algebra, trigonometry, calculus, and statistics. It also links out to practice problems and videos for the topic at hand, which helps older kids who got stuck on linear equations walk through similar problems after the solver shows the method.
Price: Completely free, no in-app purchases.
6. Todo Math
Ages: 3 to 8 Platforms: iOS, Android
Todo Math is designed for the preschool through second-grade window and covers early math concepts through short, cheerful mini-games: counting, number recognition, addition, subtraction, place value, and simple word problems. The free version includes a Daily Mission, a short bundle of activities perfect for a 10 minute sit-down after dinner. Instructions are mostly visual and voiced, which helps children navigate the app before reading comes online. A four-year-old can play on their own without an adult reading the screen for them.
Price: Free Daily Mission; Todo Math Family subscription unlocks the full library (check current pricing in the app).
7. DragonBox Numbers and DragonBox Algebra
Ages: 4 to 9 (Numbers), 5 and up (Algebra) Platforms: iOS, Android
A fair note: DragonBox is paid, not free, but it belongs on any list of apps worth their price. The games teach algebra through puzzles before the child knows they're doing algebra, and Numbers teaches the composition of digits through colorful creatures children can combine and split. The real challenge DragonBox solves is the one most math games skip: building the mental model behind an operation, not just drilling it. If a parent is going to pay for one math app for their children, this is the one to consider for conceptual depth rather than drill.
Price: One-time purchase per title (check current pricing in the app).
Which free math app matches your situation?
Here are some concrete ideas for matching a free math app to your situation. The right approach depends on which fight you're actually trying to end.
Your child dislikes math and refuses to practice. We recommend starting with MathHero or Prodigy. These two math games change the question in your child's mind from "will you do math today?" to "can I play?" Over a week or two, that difference compounds and the daily fight goes away.
Your child needs help with homework tonight. Download Photomath or Microsoft Math Solver. Sit with your child the first few times so the step-by-step solutions work like a tutor session rather than an answer key. Both tools help your child understand where their reasoning broke down.
You have a preschool-aged child. Khan Academy Kids or Todo Math. Both are built for ages where reading is still shaky and instructions need to be audio, and both help children get comfortable with numbers before formal school.
Your child is studying for tests. We recommend the main Khan Academy app for the deepest practice library and the clearest progression for self-study. Add Microsoft Math Solver as a backup tutor for problems they get stuck on.
Your child clicks with puzzles. DragonBox is worth the one-time download cost for how it builds concepts and the slow, playful approach to algebra.
Common questions
Which learning app is completely free? Khan Academy and Microsoft Math Solver are completely free with no ads and no in-app purchases. Khan Academy Kids is also entirely free for ages 2 to 8. If you want ongoing math practice specifically for ages 5 to 10, MathHero is free for five levels per day with no locked content.
Is there a free version of Mathletics? Mathletics is a subscription product and does not offer a permanent free consumer tier. Some schools provide access through a license, which can help families whose child already uses it in class. For a free alternative with similar curriculum breadth, Khan Academy is the closest match.
Is Photomath still free? Yes. The core camera-based solver and basic step-by-step solutions remain free. The Photomath Plus subscription adds animated explanations and textbook solutions.
Which study app is 100% free? For general study, Khan Academy. For math specifically, Microsoft Math Solver is also 100% free.
A short note before you install anything
A math app is a tool, not a tutor. Even the best free math apps work best alongside a parent who checks in on what their children are practicing, notices the topics where kids slow down, and celebrates streaks. Pick one or two to download, not seven. Try one for a week. If your child is asking to open the app on their own, you found the right fit, and that one tool will help more than any three others gathering dust on the home screen. The best apps on this list are not the ones with the most polished ideas; they're the ones your child actually opens tomorrow.
