User reviews

No user friendly

eTextbook limited printing copies ( 10 max per book). Difficult to navigate among pages. Terrible app

Awful

Clunky and awkward. Can’t scroll pages like in kindle. Have to tap the arrows. Doesn’t seem to save my place. If I accidentally close the app, I lose my place every time. It’s very stressful. I am using this app for a PhD course and I’m afraid I’m going to fall behind because I lose so much time fighting from this app.

App struggles to save notes

I’ll highlight text and attach a note to said highlights. However, whenever I reopen the app all of my notes are gone. The Highlighted text are still lit but then note associated with it are just gone.

Lags a lot

Started using Kortext for school and every time i try and use it I have to repeatedly close it out or shut it down since it won’t stop freezing or lagging

Useless

I had to buy an expensive textbook for a class, tried using the app to get full functions, and it has me going in circles to keep signing in. Can’t do anything on the app, without signing in to utilize the textbook. However, the app won’t sign you in.
