It can be used as an app on both macOS and iOS, as well as a website on any computer. Dropshare allows users to share files and folders directly from their Dropbox, Google Drive, OneDrive, or ownCloud account, or by uploading the files to its own secure file storage. It also provides a secure link to share files with others, as well as an encrypted file storage option to protect sensitive data. Additionally, Dropshare offers detailed analytics on who has accessed your shared files, as well as a password protection feature for extra security.
