تهجد is an Android application developed by Samer F. Lulu, designed to simplify the recitation of the Quran during Tahajjud prayer. This app provides a convenient way to read the Quran with minimal movements and offers features such as surah, juz, and hizb indexes, bookmarking, and a simple layout with distinct and clear color-coded verses for comfortable nighttime reading.

The app's main feature is the automatic scrolling with different speeds, allowing for hands-free reading. The app also offers a one-touch play and pause function. The Quranic text used in the app is a verified electronic version of the Mushaf Al-Madinah, written in the Ottoman script, by King Fahd Complex for the Printing of the Holy Quran.
