# EastarJet vs 유심사

The clearest difference is review sentiment: 유심사 at 98% against EastarJet's 7%. 유심사 also leads on rating (4.9 vs 1.0) and ratings volume (32 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

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

유심사 holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: 유심사 has 32 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 7% of EastarJet's written reviews are positive against 98% of 유심사's.
