# FluentJoy vs Cosmo (formerly ClassUp)

The clearest difference is rating: FluentJoy at 4.8 against Cosmo (formerly ClassUp)'s 4.5. FluentJoy also leads on ratings volume (6.5K vs 914). Cosmo (formerly ClassUp)'s advantage is review sentiment (80% vs 69%) and iOS requirement (15.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. FluentJoy sells 21 in-app purchases, starting at $9.99 per month and Cosmo (formerly ClassUp) sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

FluentJoy holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: FluentJoy has 6.5K ratings behind it against 914, so its average is the more settled of the two. Written reviews complicate that: 69% of FluentJoy's written reviews are positive against 80% of Cosmo (formerly ClassUp)'s, so the app with the better star average is not the one people write more warmly about.

FluentJoy ships an update weekly, Cosmo (formerly ClassUp) every 9 days. Both last shipped on October 30, 2026.
