As a user I will advise against it.

If I want to learn writing Arabic or Arabic phonetics, I will rather use a different app.

I want this app only for one single purpose, learning Qur'anic Arabic ( vocab+ grammar).

Why?

Because I am sure there is not more than 1 or 2 engineers working on this app.

may be just 1, and that too part-time. These apps are not built by Google or Microsoft or Apple companies who have 100+ people working on this app.

Given that resources are so limited, this app should focus on just one thing.

Because they can only deliver maybe 6 features per year.

There are other apps for learning to read and write Arabic letters.

There are other apps for prayer reminders

There are other apps for the Book of Hadeeth

Let's use those apps.

For the sake of ummah, let's not become demanding and ask everything in one app. Let's not ask them to build a multi-purpose app.
