# EQ560 vs 钢琴巴士

The clearest difference is rating: EQ560 at 3.7 against 钢琴巴士's 1.0. EQ560 also leads on ratings volume (30 vs 1) and review sentiment (60% vs 44%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. EQ560 sells 1 one-off in-app purchase and 钢琴巴士 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

EQ560 holds the better App Store score, 3.7 against 1.0. That said, the two scores are not equally well evidenced: EQ560 has 30 ratings behind it against 1, so its average is the more settled of the two.
