The app shows how many times any root is found in how many derived forms.
But it doesn't mention the names of all derived forms (like corpus.quran.com, Al Qur'an search and browse by Bismillah Android, etc).
There are lots of Quran apps. Some are proficient in the Dictionary, some give importance to tafsir, some give importance to grammar, some focus on Qur'an searching – all are different in purpose.
But no app in which all features are available together.
The only app by GTAF gives satisfactory results up to a certain limit, but does not fulfil the requirements of studies.
This improvement on the Dictionary/Word occurrences list is important.
If you please mention the names of form of all derived formats, it should be the best and most advanced level.
Please take a look at the screenshots.
