The 1.2 version of CudaSign for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. CudaSign for Mac lies within Productivity Tools, more precisely Cloud Services. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This free software for Mac OS X was originally produced by Barracuda Networks, Inc.
From the developer:
CudaSign enables users to right-click on documents from Finder and to upload them directly to CudaSign. Rather than opening up a web browser and visiting the CudaSign app to upload a document, it now takes a matter of seconds to navigate to the file and share it to CudaSign. An icon is accessible from the menu bar, providing quick links to documents and templates that are stored in the user’s CudaSign account.
You may want to check out more Mac applications, such as CrowzNest, SendGenie or CloudySafe, which might be similar to CudaSign.
