# Sound Button World vs Reverse Singing

The clearest difference is rating: Reverse Singing at 4.7 against Sound Button World's 3.6. Reverse Singing also leads on ratings volume (7.8K vs 28) and chart position (#64 vs unranked). Sound Button World's advantage is in-app purchases (none vs 6) and review sentiment (57% vs 25%). On price, ads and device support there is nothing between them.

Both are free to download. Reverse Singing sells 6 in-app purchases, starting at $4.99 per 7 days. Sound Button World asks for nothing beyond the download.

Reverse Singing holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: Reverse Singing has 7.8K ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 57% of Sound Button World's written reviews are positive against 25% of Reverse Singing's, so the app with the better star average is not the one people write more warmly about.
