Analyzes a desktop browser's exported bookmarks HTML file for invalid URLs. The resultant invalid bookmarks HTML file, annotated with reason-invalid messages, is used to manually correct the browser’s bookmarks. At any time, the bookmarks file and the invalid bookmarks result file can be inspected. The in-progress validation process can be aborted.

In-app documentation includes a Quick Guide, a User Guid, an on-demand Tour Guide and help tips.

Note: Browser bookmarks files need to be placed in a "Bookmarks Validator" folder. On an iOS device, this folder resides in the Documents folder. On a macOS device, this folder resides in the Downloads folder. On iCloud, it resides in the iCloud Drive. The User's Guide provides instructions on how to set this up.
