# READING & vs 똑서

The clearest difference is rating: READING & at 3.4 against 똑서's 2.3. READING & also leads on in-app purchases (none vs 3) and ratings volume (10 vs 3). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. 똑서 sells 3 in-app purchases, starting at $6.99 per month. READING & asks for nothing beyond the download.

READING & holds the better App Store score, 3.4 against 2.3. Both are backed by a comparable volume of ratings — 10 and 3 respectively. Written reviews complicate that: 79% of READING &'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.

READING & ships an update every 2 weeks, 똑서 every 3 weeks. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
