BBConnect is the virtual classroom app for Best Brains Learning Centers. This app hosts weekly online classes connecting 1 real, certified teacher with up to 3 students per class for weekly Math and English lessons. Students work on assignments and receive feedback from teachers in real time! Teachers also monitor periodic tests to measure improvement in your child’s knowledge. Students are assigned daily homework to be completed on the app using an Apple Pencil or stylus. These 15-minute per day, per subject lessons strengthen understanding and promote retention of concepts. Homework is graded weekly to check progress. Each student works at their own pace, improving their Math and English skills one concept at a time. WHAT DO PARENTS SAY ABOUT BEST BRAINS? *Over 95% of students earn BETTER GRADES after starting classes *9 out of 10 Best Brains students OUTPERFORM their peers in Math *9 out of 10 Best Brains students OUTPERFORM their peers in English WHAT IS BEST BRAINS? Best Brains is an after-school learning solution for kids as 3 years old to 14 years old. Students are taught Math and English in weekly, online lessons with state-certified teachers with up to 3 students per class. Students receive 1-on-1 instruction on new concepts, and complete daily homework that is interactive and non-repetitive. Students are graded on their performance weekly, and are tested periodically to assess improvement. Students must perfect each concept before moving on, to ensure better performance in the classroom and higher test scores. WHO TEACHES VIRTUAL CLASSES? All Math and English classes are taught by certified teachers who have earned teaching licenses from state and provincial boards. Students are paired with teachers local to their area when possible, and sit with the same teacher every week in scheduled time slots. All of our Best Brains teachers are based in the US and Canada, and undergo background checks before being hired. Most teachers work full time in private and public schools in North America, providing tutoring assistance to Best Brains students during the evenings and weekend. WHAT DOES BEST BRAINS USE TO TEACH STUDENTS? Best Brains uses a unique curriculum developed by teachers to support a child’s schoolwork. Each week, a new concept is introduced to the student by their teacher, which they practice throughout the week. During each course level, a child’s knowledge builds on itself, reaching higher and higher. Most students work above grade level, keeping their minds active with advanced material and earning better report cards at school. You can also enroll your child in Best Brains if they need extra support to bring them back up to grade level so that they don’t fall too far behind. Our approach is ideal for every student through the use of methodical, incremental learning.

ReceptionRating · Positive reviews · Number of ratings

Cosmo (formerly ClassUp) holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Cosmo (formerly ClassUp) has 914 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 100% of Best Brains bbConnect's written reviews are positive against 80% of Cosmo (formerly ClassUp)'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Best Brains bbConnect ships an update every 3 months, Cosmo (formerly ClassUp) every 9 days. The most recent releases landed on September 22, 2026 and October 30, 2026 respectively.
