Pingling 1.0 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X is a product of Graham Parks. 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 program lies within Internet & Network Tools, more precisely General.
From the developer:
Pingling is a dockling that uses ping to test whether or not you have a working connection to the internet. It shows the status of your connection in the Dock on a second-by-second basis. Great for Wi-Fi users.
