Brilliant vs Monster Math

Brilliant is an interactive STEM learning service with courses in math, coding, data science, science, technology, and AI. Learners work through problems, explore visual models, and receive immediate feedback. Most courses include Koji, a digital tutor that guides learners through reasoning step by step. Free accounts can access all courses but are limited to two lessons per day in sequence, see occasional ads, and receive only a limited Koji preview. Premium adds unlimited lessons and practice, the option to jump to any lesson, an ad-free experience, and full Koji access. Individual Premium is listed at $20 a year, billed as one payment and renewed annually; Family Premium is $40 a year, also billed as one payment and renewed annually, with six seats included. Eligible K–12 teachers and their students may receive free Premium through an application-reviewed educator program. That program supports Google Classroom roster syncing and lesson sharing. Its reports show lesson completion, time spent, course progress, and completion dates, but not answer-level correctness or formal grades. Brilliant runs on Android, iOS, and web, and lessons require an internet connection and cannot be downloaded.

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.
