Asad's translation and commentary is the most well researched and well thought out available and this app makes it so conveniently accessible. Everything is included, including the forward and Asad's very helpful appendices. The app can be configured to show the Arabic, the translation, and the commentary together on the screen, just as it appears in the hard copy. The only difference is that this doesn't weigh 6 pounds. Oh, and the app also allows listening to the recitation while the relevant verse, translation, and footnote are automatically scrolled to and highlighted.
One relatively small issue is that the auto scrolling can be a bit frustrating at times. For instance, if you have a verse selected and then try scrolling, you're taken back to the selected verse while you're trying to look at another verse. Or if you're following along with the recitation and come to a verse without a footnote, the footnotes section automatically scrolls to the top.
Overall, though, this is a brilliant app.
