Monster Math vs Zearn Math

Monster Math is a math-learning app for elementary learners, focused on K–3 math fact fluency from number sense through multiplication. Its guided lessons and practice adapt difficulty to the learner and follow Common Core progressions for that scope. The design uses calm visual practice without timers or loud sounds, and parent reporting is included. The recommended daily practice is about 10–15 minutes. It runs on Android, iOS, and the web.

The free plan costs nothing and allows 10 levels per day. Premium costs $59.99 a year, billed yearly, equivalent to $4.99 a month; it includes all features, levels, and content, progress tracking, and ad-free offline play. A seven-day trial offers full access and requires a credit card to start; there is no charge if canceled before the trial ends. The app is listed as ESSA Tier IV Certified. The company is Makkajai Edu Tech Pvt. Ltd., and its site provides a Contact Support option.

Zearn Math is a web-based platform for students in grades K–8, used alongside teacher-led instruction. It provides more than 1,000 digital lessons arranged in Missions covering major K–8 mathematics concepts.

Teachers can view progress in real time and use reports to identify where students need help; gamified practice and parent reporting are listed capabilities. School Accounts integrate with Clever for roster management and login. Zearn says it does not sell student information, use it for advertising, or use personally identifiable information to train AI models, and cites FERPA and COPPA. Listed safeguards include encryption in transit and at rest, two-factor authentication, security updates, risk assessments, and vulnerability remediation. There are no student-facing AI, chatbots, messaging, or social networking features.
