The 2.8 version of AppSana 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. The application lies within Productivity Tools, more precisely Office Tools. This software for Mac OS X was originally created by Emre Oktem. We recommend checking the downloaded files with any free antivirus.
From the developer:
AppSana is a simple and exclusive navigator for Asana. Therefore, you don’t need to keep your main browser open just for Asana. AppSana remembers the last page you have visited. In addition, it can inform you about every activity on your Asana projects. It lets you upload files easily.
