# Kotlin Recipes vs CraftOS

The clearest difference is monetization model: CraftOS at free against Kotlin Recipes's free with in-app purchases. CraftOS also leads on rating (4.8 vs 4.5) and iOS requirement (13.0 vs 17.0). Kotlin Recipes's advantage is review sentiment (100% vs 88%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Kotlin Recipes sells 5 one-off in-app purchases and CraftOS sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CraftOS holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 8 and 17 respectively. Written reviews complicate that: 100% of Kotlin Recipes's written reviews are positive against 88% of CraftOS's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 months. Both last shipped on October 30, 2026.
