معلم التجويد - جزء عم is an Android app developed by BakkaSoft under the Education & Reference category. The app aims to facilitate Quranic recitation for beginners and intermediate reciters who may not be well-versed in the rules of Quranic recitation. The app uses colors to differentiate between the nine sections of Quranic recitation rules. Each section is thoroughly explained with a statement of the rules it contains and what is excluded from it to avoid confusion for the user. The app includes 29 comprehensive lessons on the rules of Quranic recitation, with exercises for each lesson consisting of four types of questions: multiple-choice, true/false, matching, and fill in the blanks.

The app also includes a section on articulation points and their descriptions, with examples and pronunciation of the letters with movement. Additionally, the app features the Baghdad electronic Quranic recitation with the voice of Sheikh Ibrahim Al-Akhdar, a renowned Quranic reciter from the Prophet's Mosque in Medina. Finally, the app includes a colored display of Juz Amma, the 30th chapter of the Quran, with rules of Quranic recitation applied through the use of colors.
