Partially work

I was getting ready to send it back and decided to try once more.I do see some of the photos and videos that it transferred. But they also still showing on my iPad mini. I don’t understand that. The app itself doesn’t work with the usb flash. It doesn’t work at all with my iPhone 16 pro. I’m still trying to work with it because of some transfers. Overall I’m not satisfied with it. A 1TB flash.

The app was amazing before.

The application has several issues with the advanced updates. First, there is a bug in the dark mode. Second, there is an inability to share files with other applications. Third, and most importantly, the file locking tool with a password has disappeared.

I hope the issues are fixed so we can use your company's tools.
التطبيق فيه عدة مشكلات في التحديثات المتقدمة منها اولا هناك خلل في الوضع الداكن ثانيا عدم القدرة على مشاركة الملفات مع التطبيقات الاخرة ثالثا وهو الاهم اختفاء اداة قفل الملفات بكلمة سر

ارجو اصلاح المشكلات لكي نستخدم ادوات شركتكم .

Very limited & poorly presented

App can’t even handle files a few hundred MB large? What is this? The late 90’s ?? Good thing I only tried the app and didn’t buy their product. It can only open large files, but nothing else.

Crashes

When I got the new iPhone 14, this app crashes. Now I can’t back up my phone. Is there an issue with new iPhone and this?

Why don’t this work anymore?

I’ve got my flash drive for iOS and it is still able to be loaded on a PC but the app is dead weight on my phone and has been for a year or two. I hate to lose any data that I’m not able to offload on the drive….
