# EBS 초등 vs Buff

The clearest difference is rating: Buff at 3.5 against EBS 초등's 2.9. Buff also leads on update cadence (every 3 weeks vs every 2 months). EBS 초등's advantage is review sentiment (82% vs 43%) and ratings volume (27 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Buff holds the better App Store score, 3.5 against 2.9. That said, the two scores are not equally well evidenced: EBS 초등 has 27 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 82% of EBS 초등's written reviews are positive against 43% of Buff's, so the app with the better star average is not the one people write more warmly about.

EBS 초등 ships an update every 2 months, Buff every 3 weeks. The most recent releases landed on October 14, 2026 and October 17, 2026 respectively.
