This includes the Geneva Conventions and their Additional Protocols, the ICRC’s original and updated commentaries on the conventions and additional protocols, and the rules of customary IHL identified by the ICRC’s 2005 Study on Customary IHL. The app aims to support the promotion and implementation of IHL worldwide by providing easy access to IHL treaties and rules in six languages. It also allows users to search and find specific information, bookmark documents, and share content through email and social media. The app is free to download and is compatible with Android 9.0.
