It fits for my purposes!

I love that I can download a class PDF and edit them on this app! As a student that’s all I really needed so I’m pleased that the bare minimum is free.

If I had to give one complaint it would be the functioning of the voice over that reads the document for you. When I change the speed of the voice over, after listening to it 2 to 3 pages in, I’ll find that I need it to read at a faster pace. But, when I change the speed it starts again at page 1. I’ve tried to highlight and select “speak” on my iPhone but it doesn’t work.

Other than that this app is exactly what I needed and the voice over would have just been an added bonus.

Cannot restore files at new iPhone X and the paid app was not exist anymore.

I paid a one time version for more storage several years ago and I didn’t know that the files could not transfer to my new Iphone X from my old Iphone X (same model) this year. I still could do that one year ago. It used to restore files automatically, but not anymore. It created so much trouble. Now they require to subscript the Kdan cloud service to store the files according to the app introduction. Some reviewers complained that it was hard to cancel their subscription. My husband backed up my old phone with PC and restored to my new phone. The app on my new phone just showing freeze and could not complete the downloading. I realized that the paid app I purchased was not exist anymore, only the free one.

Per the instruction that showed on reviews, my husband followed the steps to restore my files, but they could not be open because they required me to subscript their cloud service to have more space. What a pain! My old paid app had more space for all my files. They deleted my paid app a few years later and asking for more money to replace. I think this is not the right way to do the business, made me feel I got cheated, so I would not suggest this app to anyone.

Used to love it

This used to work well for me, but lately not so much. It have a bill that was emailed as a PDF and I can’t open it on my iPhone 13. pro max. I’ve had to forward it to an associate to open and print it for me. This has happened to me on other occasions also. Also, over the past year, I have had trouble working with it on my iPhone and iPad. Maybe it is easier to use with a laptop or desktop, but I don’t have either of those functioning right now. I had an email from them to sign into my account this morning, which I did. It appears they are making changes and I am not willing to pay more, that is one reason I quit Adobe. It isn’t something I need often anymore, so I am not willing to increase or renew unless it starts working much better very soon.

Developer Response ,
