Synthesis Tutor review

Synthesis Tutor is the only tool here built for young children, and it treats math as a series of interactive lessons rather than a chat. The company says it is designed for ages 5 to 11 and covers the standard K-5 math curriculum, from counting and cardinality to fractions and algebraic thinking. The tutor adapts as the child works, surfaces mistakes and targets gaps in knowledge, while parents get progress reports. One family plan covers up to 7 children, which makes it cheaper per child than most apps: $119 billed annually, which Synthesis says equals $9.92 per month, or $29 billed monthly. A 7-day free trial starts without a credit card. The tradeoff is scope. It does not help with a specific worksheet a teacher sent home, it stops at elementary math, and older students will outgrow it quickly.
