The جامع متون شيخ الإسلام محمد ابن عبد الوهاب app, developed by So Smart Apps, is a free educational reference application available on the Android platform. This app has a collection of books and texts written by Sheikh al-Islam Muhammad ibn Abd al-Wahhab, including texts such as "Usul al-Sunnah," "Al-Usul Al-Thalathah," "Al-Radd 'Ala Al-Rafidah," "Al-Qawaid Al-Arba," and "Adab Al-Mashy Ila Al-Salah."

One of the significant features of the app is the ability to change the font size, color, and style, which includes eight Arabic fonts. You can also choose from hundreds of background colors and dozens of themes, as well as select from tens of pictures as a background. The app has a side menu that contains all the chapters for easy navigation and arrows at the end of each section for easy transition to the next and previous chapter. Additionally, users can search within the book, chapter, or entire library, and save their favorite chapters and notes.
