I use PDF expert 5 or should I say I used to? :)

I am a heavy user of text to speech. I like to listen to my material. It helps me understand the text better and at a faster speed. This way I am able to go through the material several times over (while playing, pausing ).

Having understood the material, I start making flashcards using margin notes.

What I am saying is I am still partially dependent on PDF expert 5 which runs in the background while I make the flashcards on margin notes app.

Also the play/pause, go back to previous page and go back to next page is controlled by bluetooth keyboard. or by the remote that comes with earphones. There is a separate bluetooth remote especially for this purpose called "Satechi Bluetooh media remote".
