The 1.1 version of Dougler 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. 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. The application is included in Internet & Network Tools.
From the developer:
Dougler will work for all your downloading needs. Dougler will not take up more than 10% of your CPU cycles and memory. It is also very convienient as it will not interrupt your Web browser no matter what browser you use.
