The 1.2 version of HottestCorners 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. We recommend checking the downloaded files with any free antivirus. This free software for Mac OS X was originally designed by Baltic IT Solutions OÜ.
From the developer:
HottestCorners is a tiny menu bar app that allows you to run applications installed on your computer by moving the mouse pointer to any screen corner. It comes with separate control for Upper Left, Upper Right, Lower Left and Lower Right corners. The tool operates seamlessly when any additional external display gets connected or disconnected. Optionally, you can pause HottestCorners when you don't need it.
