# Busuu vs Mimir Mental Math Lite

The clearest difference is rating: Busuu at 4.7 against Mimir Mental Math Lite's 3.0. Busuu also leads on update cadence (weekly vs every 15 months) and ratings volume (101K vs 2). Mimir Mental Math Lite's advantage is in-app purchases (none vs 15) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. Busuu sells 9 in-app purchases, starting at $6.99 per month. Mimir Mental Math Lite asks for nothing beyond the download.

Busuu holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Busuu has 101K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 85% of Busuu's written reviews are positive against 92% of Mimir Mental Math Lite's, so the app with the better star average is not the one people write more warmly about.

Busuu ships an update weekly, Mimir Mental Math Lite every 15 months. The most recent releases landed on September 28, 2026 and September 17, 2026 respectively.
