Our goal is simple: make math as beloved as the bedtime story. Unlike most educational apps, the Bedtime Math app is designed for parents and kids to do together – at bedtime or anytime! It’s a free, simple tool proven to boost kids’ math skills an extra three months in one school year. How? By making it a conversation, we help kids get to the right answer – and understand how they got there! First, read the short story to your kid. We cover everything from flamingoes to pillow forts to chocolate chips. Then read the question and talk through the reasoning. Targeted for families with kids ages 3-9, each post comes with three questions at different levels of challenge. Start with the “Wee Ones” and work your way up to “Little Kids” and “Big Kids,” go as far as your kid wants to go! Often there’s a harder “The Sky’s the Limit” level for extra challenge. Do the math problem of the day or search over 1,000 math problems by skill or topic. Bedtime Math encourages a dialogue between parents and kids about real-world math. Make it a part of your family’s routine today!

Verdict

The call

The clearest difference is in-app purchases: Bedtime Math at none against Monster Math 2's 5. Bedtime Math also leads on review sentiment (85% vs 63%). Monster Math 2's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (6.5K vs 61). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Monster Math 2 holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Monster Math 2 has 6.5K ratings behind it against 61, so its average is the more settled of the two. Written reviews complicate that: 85% of Bedtime Math's written reviews are positive against 63% of Monster Math 2's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Bedtime Math ships an update every 4 months, Monster Math 2 fortnightly. The most recent releases landed on September 19, 2026 and September 22, 2026 respectively.
