Boddle vs Brilliant

Boddle is a K–6 learning game with math, English language arts, and science content for classrooms, families, and homeschoolers. Its learning roadmap adjusts material to a learner's performance. Student tools include text-to-speech, question explanations, a sketch scratchpad, and placement testing. Teachers can assign standards-aligned skills and review mastery reports by student, skill, and standard. Google Classroom and Clever provide single sign-on and roster syncing. The premium page describes more than 2,000 skills and over 48,500 questions, rationales, and explainer videos. Boddle says its full learning platform is free for every teacher and school, with Premium as an optional add-on. The Basic plan includes all learning content and more than 35,000 questions for students. Listed Premium prices are $4.08 per month billed annually and $9.99 per month billed monthly. Boddle runs in web browsers on Chromebooks and laptops, with iOS 12+ and Android 9+ apps. It states that it complies with COPPA, FERPA, and SOPPA and holds KidSafeSeal certification.

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.
