Yes. We will eventually charge for our services. But since we're still in beta mode (testing phase), your children can use this site as much as you wish.
We only have an Android app published today. We will eventually build an iOS and maybe a Windows app in early 2016 if there is sufficient demand for it. For now, download the Android app here.
We'll setup a bio page soon. For now, most of us are parents of elementary school children who are facing the challenges of raising them in a non-Arabic environment and helping them understand what they're memorizing in school. Our team is scattered between the U.S. (Washington, California), Pakistan and Egypt. And yes, we're a mixture of Arabic and non-Arabic speakers and so do understand the challenges of understanding the Quran in Arabic.
