Six Kalimas of Islam is an Android app developed by El-Saadi Digital that aims to help Muslims learn and recite the six kalimas of Islam. The app is free and falls under the Education & Reference category.

The Six Kalimas of Islam are six essential parts of one's religious belief, mainly taken from hadiths. The first one, known as the "Kalimat Tayyibah" or "word of purity," is followed by the Shahada, Tamjeed, Tawheed, Istighfar, and Radde Kufr. The app provides users with an easy-to-use interface that allows them to read and listen to the six kalimas with proper pronunciation and translation. It also includes a brief explanation of each kalima for better understanding. The app is compatible with Android 13.0 and above.
