# Java to Kotlin vs Kotlin Tutorial

The clearest difference is in-app purchases: Java to Kotlin at none against Kotlin Tutorial's 1. Java to Kotlin also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Kotlin Tutorial sells 1 in-app purchase, starting at $0.99 per month. Java to Kotlin asks for nothing beyond the download.
