# 브레인메이트 vs 똑서

The clearest difference is rating: 브레인메이트 at 5.0 against 똑서's 2.3. 브레인메이트 also leads on monetization model (free vs freemium) and update cadence (weekly vs every 3 weeks). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. 브레인메이트 sells 2 in-app purchases, starting at $9.99 per month and 똑서 sells 11 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

브레인메이트 holds the better App Store score, 5.0 against 2.3. Both are backed by a comparable volume of ratings — 2 and 3 respectively. Written reviews complicate that: 78% of 브레인메이트's written reviews are positive against 84% of 똑서's, so the app with the better star average is not the one people write more warmly about.

브레인메이트 ships an update weekly, 똑서 every 3 weeks. The most recent releases landed on September 11, 2026 and September 24, 2026 respectively.
