# K vs Cosmo

The clearest difference is rating: K at 4.7 against Cosmo's 3.8. K also leads on ratings volume (7.6K vs 283). Cosmo's advantage is ads (none vs shown). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. K sells 5 one-off in-app purchases and Cosmo sells 14 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

K holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: K has 7.6K ratings behind it against 283, so its average is the more settled of the two. Written reviews point the same way: 66% of K's written reviews are positive against 58% of Cosmo's.

K ships an update every 2 weeks, Cosmo every 8 days. The most recent releases landed on October 31, 2026 and October 30, 2026 respectively.
