# EBSi 고교강의 vs U

The clearest difference is rating: U at 3.8 against EBSi 고교강의's 3.0. U also leads on monetization model (free vs ad-supported) and iOS requirement (13.0 vs 15.0). EBSi 고교강의's advantage is update cadence (monthly vs every 3 months) and ratings volume (15 vs 5). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

U holds the better App Store score, 3.8 against 3.0. Both are backed by a comparable volume of ratings — 15 and 5 respectively. Written reviews complicate that: 36% of EBSi 고교강의's written reviews are positive against 29% of U's, so the app with the better star average is not the one people write more warmly about.

EBSi 고교강의 ships an update monthly, U every 3 months. The most recent releases landed on October 19, 2026 and October 14, 2026 respectively.
