A free app for Android, by MUMTI.ORG.
The app contains all the most important duas and invocations, for both adults and children. It has a very simple and intuitive user interface, which makes it very easy to use.
For every Duah, you will find the following information:

Transliteration: If you don't know how to read the Arabic script, this is the best option for you. With this, you will be able to read all the Duahs easily and understand them.
Illustrations: All the Duahs have illustrations, which make them more interesting and easier to understand.
Audio recitation: Every Duah has its own audio recitation, which allows you to listen to it and memorize it.
Duas for Kids: All the Duahs for kids are based on the ones for adults, but they are adapted for children.
