# 해커스 ONE vs 시원스쿨 플러스

The clearest difference is rating: 시원스쿨 플러스 at 4.6 against 해커스 ONE's 3.5. 시원스쿨 플러스 also leads on ratings volume (70 vs 10). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. 해커스 ONE sells 4 one-off in-app purchases and 시원스쿨 플러스 sells 4 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

시원스쿨 플러스 holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: 시원스쿨 플러스 has 70 ratings behind it against 10, so its average is the more settled of the two.
