Frequency
System Requirements
Frequency comes in two versions, Mac OS X and Windows2000/XP. If your computer meets the requirements for the operating system, Frequency should run fine.
You must also have a weblog account. If you don't have one, you can sign up for one here for free. Frequency has been tested with Blogger, Radio, Movable Type, pMachine, GeekLog (with the Blogger API plugin), EraBlog.NET, WordPress, Nucleus, and b2evo. Please see Weblog System Support (PDF Download) for more information.
For Mac OS 9 users, version 1.6 is still available on the downloads page.
