# Kotlin Recipes vs Developer Laboratory

The clearest difference is price: Kotlin Recipes at Free against Developer Laboratory's $0.99. Kotlin Recipes also leads on review sentiment (100% vs 60%). Developer Laboratory's advantage is update cadence (monthly vs every 4 months) and iOS requirement (12.0 vs 17.0). On rating, ratings volume, ads and in-app purchases there is nothing between them.

Kotlin Recipes is free to download; Developer Laboratory costs $0.99 up front. Kotlin Recipes sells 5 one-off in-app purchases and Developer Laboratory sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Written reviews complicate that: 100% of Kotlin Recipes's written reviews are positive against 60% of Developer Laboratory's, so the app with the better star average is not the one people write more warmly about.
