# Rulo vs Oxytone

The clearest difference is rating: Rulo at 4.9 against Oxytone's 4.5. Oxytone's advantage is ratings volume (97 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Rulo sells 1 one-off in-app purchase and Oxytone sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Rulo holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Oxytone has 97 ratings behind it against 7, so its average is the more settled of the two.
