SixtyFour presents a list of 64-bit apps that can open in 32-bit mode and facilitates the setting of a preference to force a listed app to open in 32-bit mode.

An app opened in 32-bit mode uses significantly less memory than when opened in 64-bit mode.

Running most if not all apps in 32-bit mode on systems that have little memory available could potentially lead to an increase in overall system performance.
