Assalamualaikum brother. Your AlQuran app helps me alot. May Allah rewards you.

You can however make the app better if you make the 'Note' section much bigger, maybe a full page, for easy typing and reading of notes made by users. Even better if can you add editing features in the note section, for eg. putting bold, italic, bullets, font size, undo, highlight color etc. This may help a lot for users to include comments/opinions by other mufassirs and scholars. It can also help readers or teachers to include their personalize notes.
