ODAT Tracker was reinvented from the ground up for OS X 10.7-10.9, but also runs on Mac OS X 10.6. The app allows you to choose which sites you want to follow, and will automatically update with new deals as they go live. You can set keywords to fine tune deal alerts, and choose to have deal windows pop forward on the screen and fade back off. Use Notification Center on OS X 10.8 (Mountain Lion) and 10.9 (Mavericks) to receive alerts directly from the OS. Tap any deal to go directly to the merchants site and make a purchase. ODAT Tracker makes it easy to stay on top of all the ODAT sites and daily deals at once!

iPhone, iPod, and iPad users, be sure to check out ODAT Tracker in the iTunes App Store.
