Risale-i Nur - Rnk, an educational and reference application developed by RNK Neşriyat, offers a comprehensive platform for reading and listening to the Risale-i Nur collection. Authored by Bediüzzaman Said Nursi, this app serves as a Quranic exegesis that proves and explains faith truths with rational evidence. The app includes features such as the Quran, various prayers and devotions, the Risale-i Nur collection, and books from the Ottoman Turkish Risale-i Nur collection.

The app provides a reading module with detailed book indices for easy navigation, night mode, word meanings from a glossary while reading, and the ability to view translations by clicking on Quranic verses and Arabic phrases (under development). The listening module allows users to download and listen to audio recordings from the Quran, Hizb-ül Hakaik, and Risale-i Nur, with options for different playback speeds. The search module enables users to search for independent words or fragments, find similar words, and easily navigate between search results and books.
