From the developer:
Disk Space is an app that shows disk drive information. This includes hard drives, external drives, network drives, DVD’s, CD’s, memory cards, and USB drives. Scan your home folders for a sortable list showing their size on your hard drive. Then single click in the scan results to drill down to subfolders.
You may want to check out more software for Mac, such as Video Disk Space Calculator, Disk Space X or Disk Space Analyzer, which might be similar to Disk Space.
