User Reviews

The U-Disk app is praised for being easy to use and for enabling photo transfers from iPhone to external storage, with compatibility to certain drives. However, reliability issues are common: it can be slow or crash, especially when videos are involved; some users report it won’t work on iPad and cannot access iPhone internal files or non-photo/doc types; drive detection can fail (external storage shows as N/A); and helpful support is lacking, with vague instructions and distant contact options. Overall, usability vs. reliability is mixed.

Pros

Easy to use app interface
Works with iPhone and lets you copy photos/files to external storage
Compatible with certain external drives (TechKey/3-in-1 thumb drives)

Cons

Slow performance and crashes (e.g., video playback)
Inconsistent device compatibility (not working on iPad; limited access to iPhone internal files and other file types)
External drive detection issues (shows as N/A or cannot detect)
Poor or missing customer support and troubleshooting resources
Occasional confusing UI/workflow that misleads about copying to iPhone

Recent reviews

For video files that probably have a format it doesn’t support, it doesn’t even display the file at all. Why not just display it so I can copy them out to internal storage.
