# Reverse Singing vs DJ Kartier

The clearest difference is update cadence: DJ Kartier at every 3 days against Reverse Singing's fortnightly. DJ Kartier also leads on review sentiment (45% vs 25%). Reverse Singing's advantage is rating (4.7 vs 4.4) and ratings volume (7.9K vs 164). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Reverse Singing sells 6 in-app purchases, starting at $4.99 per 7 days and DJ Kartier sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Reverse Singing holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Reverse Singing has 7.9K ratings behind it against 164, so its average is the more settled of the two. Written reviews complicate that: 25% of Reverse Singing's written reviews are positive against 45% of DJ Kartier's, so the app with the better star average is not the one people write more warmly about.

Reverse Singing ships an update fortnightly, DJ Kartier every 3 days. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
