# Cosmo vs Kasetto

The clearest difference is ads: Cosmo at none against Kasetto's shown. Cosmo also leads on iOS requirement (17.0 vs 26.0). Kasetto's advantage is review sentiment (100% vs 70%) and update cadence (every 3 days vs every 8 days). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Cosmo sells 1 one-off in-app purchase and Kasetto sells 6 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Cosmo ships an update every 8 days, Kasetto every 3 days. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
