10 Free Math Apps for Students that Teachers Swear By

Free math apps can give students extra practice, let them explore ideas on their own and show teachers where a class needs help. The ten tools below are free to start using as of October 30, 2026. Where a paid plan or a limit applies, the entry says so.

Some are built for classroom use, with assignments and reports for teachers. Others suit homework help, review or open-ended exploration. Start with the grade level and the job you need the app to do, then use the comparison table and the tips on choosing at the end.

1. Prodigy Game

Prodigy is a game-based math program. The company says its in-game math and English content is free, that no membership is required to use it and that teacher accounts are free too. According to its teacher FAQ, the math content covers grades 1 to 8 with more than 50,000 questions. Students can play in a web browser on computers, Chromebooks and iPads, and on Android devices, or use the iPad and Android apps.

Teachers can create assignments that put chosen skills into the game, then view reports during and after the assignment. Students take a placement test when they start playing, which sets their starting grade level. Paid memberships are optional and are not needed for the core math content.

2. Math Learning Center Apps

The Math Learning Center offers a set of free apps based on the visual models in its Bridges in Mathematics curriculum. They run as a web app in modern browsers, and many also come as iOS downloads. Number Line, Fractions, Geoboard and Number Pieces are available on the web and on iOS, while Number Chart and Partial Product Finder are web only.

The apps page lists iOS versions but no Android version, so students on Android devices and Chromebooks should use the web apps.

3. CK12

CK-12 is a nonprofit that provides free educational materials and resources. Its platform overview describes adaptive practice that gives students easier or prerequisite questions when they struggle, teacher-directed classes for assigning lessons and practice, and access on any device, including smartphones, Chromebooks, tablets, laptops and desktops.

CK-12 says its elementary coverage is more limited than its resources for grades 6 to 12, where its content is strongest. Its simulations are in physics and chemistry, so for math look to its practice and lessons instead.

4. Colorado’s PhET

PhET, from the University of Colorado, describes its work as free, interactive, research-based science and mathematics simulations. The simulations are built in HTML5, so students can use them online in a web browser, or download them to a computer. The site has a Math & Statistics section.

Check the license on each simulation before reusing it outside your own class.

5. Photomath

Photomath lets students scan a problem with a phone camera, including word problems, or type it in. It then shows a solution, sometimes with more than one method, and lets students review each step. It runs on Android and iOS. Photomath lists a free Basic plan with step-by-step explanations, custom visual aids and extra "how" and "why" tips, plus paid plans at $9.99 a month or $69.99 a year when we checked. The page lists the same features under each plan and does not describe limits on the free plan.

Because it shows complete solutions, agree on when students may use it. It works best as a way to check homework and understand steps, not as a shortcut on graded work.

6. Khan Academy

Khan Academy describes itself as a free tool for anyone, including students, teachers and parents. It lists more than 840 free courses across core academic subjects from kindergarten through early college, with math as one of the subjects. For teachers, it offers standards-aligned practice and AI support to help plan, personalize and guide learning. Khan Academy Kids is a separate app for ages 2 to 8, preschool through second grade. Khan Academy has mobile apps for iOS and Android, and progress syncs between the app and the web.

Khan Academy also appears in our list of digital home-schooling resources, which gathers more online math options for study at home.

7. GeoGebra

GeoGebra is open-source software that it describes as freely available for non-commercial users. Its tools include a Graphing Calculator, a Geometry app for constructions, a 3D Calculator, a Scientific Calculator and a Calculator Suite. GeoGebra Classroom is a collaboration platform for sharing resources and monitoring student progress in real time.

The calculators and online resources are web-based, and mobile apps are available through the Apple App Store and Google Play.

8. Desmos

Desmos describes its calculator as a free online graphing calculator. Students can graph functions, plot points, visualize algebraic equations, add sliders and animate graphs, which makes it useful for seeing how changing a value changes a graph. It runs online.

9. Brainscape Flashcards

Brainscape lets students study flashcards online or in its iOS and Android apps. Its pricing page describes the Basic plan as free forever: students can study 2,500 pre-loaded flashcards, create and share unlimited flashcards and use AI to make hundreds of flashcards. The Pro plan, shown at $7.99 a month on its yearly plan, adds unlimited AI-made flashcards, images and sounds on cards and private content.

For math, students can build decks for formulas, vocabulary and worked-example rules. Check any AI-made card for accuracy before studying it.

10. Mathway

Mathway advertises free step-by-step solutions that students can get without creating an account, on its website or in its iOS and Android apps. It also says an optional subscription unlocks the full work shown for every step, and its site does not spell out how much working is free. As with Photomath, set expectations for when students may use it.

How to choose a free math app

• Match the grade. Prodigy covers grades 1 to 8 and Khan Academy Kids is for ages 2 to 8, while CK-12 is strongest in grades 6 to 12 and Desmos and GeoGebra are built for graphing.
• Match the job. Prodigy and CK-12 Adaptive Practice are for practice. PhET, GeoGebra and the Math Learning Center apps are for exploring ideas. Photomath and Mathway are for checking work. Brainscape is for review.
• Check the device. Most of these run in a browser, and several also have iOS or Android apps; the entries above say which. Our guide to Chromebooks or iPads can help when you are choosing hardware for a classroom.
• Read the cost line. Many of these are free to start, with optional paid plans or subscriptions. Check what the free version includes before building a lesson around it.
• Check student privacy. The FTC says a school can consent for parents under the children's privacy law only in an educational context, and only when the operator collects information for the school's use and benefit and for no other commercial purpose. Under that FTC guidance, ask your school or district before assigning an app that asks students to create accounts.
