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.

Supposedly premium features with $59

I started one year subscription 2 days ago and supposedly it will be free to try for 7 days but was charged the full amount 2 days later. Also despite the $59 per year, you realize later that you still have to pay for everything such as converting document or faxing... you will still have to purchase “CREDITS” to use any of the premium features, so despite $59 you still have to pay to fax or convert document or use other premium features, so why do you charge annually $59 ? This is the worst false advertising scheme I have ever seen. Where does it say in your advertisement that you will still have to pay for all premium feature AFTER you pay $59 per year. No one like to be treated this way. No matter how good you product is, it is misleading and I will never recommend or stay with you

Fake Reviews

I purchased this app when it was a standalone app not a subscription and now it’s useless, hate companies that do this bait and switch crap and try an force you to subscription model. don’t give your money to subscription model companies they are a big fat RIPOFF. I give it ZERO STARS BECAUSE it’s WHAT IT DESERVES FOR BAIT AND SWITCH outrageously priced.
I never ever give my money to any company that goes subscription model. Eventually all companies in subscription model will fail when people stop subscribing or go broke paying for every subscription app they download. Not worth it keep your money
Developer why should I contact you about the new app when I told you I would not pay for a subscription
