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.

Older version won’t update, newer version doesn’t have my files

I have the older version that I purchased (1 time purchase ). It won’t update. So I tried the free version just to see if I can access my files. It’s a totally different look. And has none of my files. How to I get my old PDFs ? And notes ? If I could at least open my old version and save my files somewhere else I’d be ok with that. But I can’t open it. It won’t update. Very frustrated......
After reading developers response I tried hooking my iPhone to pc and iTunes. PDF reader is not listed as one of the apps that I can file share with my computer. I’ve requested more help.

Developer Response ,

Hello, we suggest you to transfer your files in old version app to PC/Mac by connecting your iOS device to your computer.
1. Launch iTunes on your computer.
2. Connect your iOS device to the computer via USB cable.
3. Scroll down to File Sharing section.
4. Then find the PDF Reader app in the "Apps" tab. Tap the app icon, and you will see all the documents stored in this app.
5. Then tap the target file and tap "Save" to export the file to your computer. Or you can tap "Add" to import files from your PC/Mac to PDF Reader app.
Hope this helps. If you have any further questions, don't hesitate to contact us at

Good app! Does the basics.

You can download files easily, search for text, highlight text, as well as all of the basic functions. However, it is difficult to email multiple documents. You have to individually email them, which is problematic if you want to send multiple files.

Developer Response ,

Hello, thank you for the review and your support. To e-mail multiple files from PDF Reader, we suggest using Drag and Drop on iOS 11. Here's a YouTube tutorial with the instructions:
