User Interface
- SizeUp
- Quickly position a window to fill exactly half the screen, a quarter of the screen or full screen ... basically replicating one of the only few worthwhile features of Windows 7, but using keyboard shortcuts.
- Moom

Retail
- Square.com
- Accept credit card payments right from your iPhone.
Security
- 1Password
- Centralize all of your website passwords and secure notes, with easy access through custom Web browser toolbars. If you have an iPhone or iPod, you can take them on the go too!
Miscellaneous

- ScreenFloat
- Create quick screenshots that float above your applications and Desktop.
Web Resources
- Alternativeto.net - Mac
