Quran with Tafsir is an iPhone application developed by Reza Ahoui that offers a complete Quran reading experience with its intuitive interface and useful features. The app contains the complete Quran, just like the actual Mus'haf, and offers Tafsir Almizan in Arabic by Allamah Tabatabaei, Tafsir Al-Amthal by Ayatollah Naser Makarem Shirazi, Tafsir Al-Noor by Sheikh Mohsen Qara'ati, and Tafsir Ahl al-Bayt (Hadith-Based) linked to each verse.

The app also provides verse-by-verse audio recitation by multiple reciters, including Abdulbasit, Al-Minshawi, Maytham Al-Tammar, and more. It has a night mode option for easier nighttime reading, a full-text search throughout the Quran and Tafsir, bookmarks for marking progress or quick access, and favorites to mark verses that the user likes. The user can copy/paste a verse or share it on social media, share audio files (recitation) on social media, zoom in/out each page, and set a reminder for daily Quran recitation. The app also displays "The Verse of The Day" daily and allows note-taking for each verse of Quran.
