# eSLS TOEIC® vs 코스모스

The clearest difference is rating: eSLS TOEIC® at 4.5 against 코스모스's 4.1. 코스모스's advantage is review sentiment (50% vs 24%) and ratings volume (303 vs 2). On price, ads, in-app purchases and device support there is nothing between them.

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

eSLS TOEIC® holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: 코스모스 has 303 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 24% of eSLS TOEIC®'s written reviews are positive against 50% of 코스모스's, so the app with the better star average is not the one people write more warmly about.

eSLS TOEIC® ships an update every 2 months, 코스모스 every 2 weeks. The most recent releases landed on October 15, 2026 and October 21, 2026 respectively.
