IlmNahw is a learning app based on the Arabic language that will teach you how to pronounce the Arabic letters correctly. It also helps you improve your speaking skills.

The app can be used in two ways:

Learning how to pronounce the letters correctly: The first thing that you need to do is to learn how to pronounce the letters correctly. This can be achieved by using the built-in voice recorder and playing it back to yourself. You need to keep practicing this until you master it. 

Improving your speaking skills: The second thing that you need to do is to improve your speaking skills. To do this, you need to practice saying the letters aloud and record the result. You need to keep practicing this until you become good at it.
