SixtyFour is a memory optimizer, created to force 64-bit apps to open in 32-bit mode for G5-based and 64-bit-capable Intel hardware low on memory.
An app opened in 64-bit mode uses significantly more memory than its 32-bit counterpart. On systems that have little memory available, it is better to open a 64-bit app in 32-bit mode. Forcing a 64-bit app to open in 32-bit mode reduces its memory usage significantly and its startup time. Eliminating the memory overhead could potentially lead to an increase in overall system performance.

The amount of "Free" RAM is not necessarily that significant - much of the RAM marked as "Inactive" is not free simply because the system has not needed it. It is better to keep inactive program code and data in RAM than flush it to disk because it may be needed again (because of a context switch for example) before a program needs totally new RAM, and that way you avoid the delay involved in getting the code/data back into RAM from the hard disk as you would get if the OS maximally flushed stuff to disk in order to maximise the amount of "Free" RAM.

After your explanation, the problem is that such caching should be always for the system itself, not for any non-system application... when you've got 4 applications cached, such cache or "inactive" memory is wasted, because in order to open another memory demanding application, such "inactive" memory must be freed, and a worst delay... and it is always better to have unoccupied memory. The memory management is horrible because it didn't happen in Tiger, in fact it should be as in the early days, load application to RAM, finish to use it and unload from RAM or if you've got to do caching, then do profiling on the applications... and by the way, the RAM initially was created to support the registers and to randomly put load and unload code...

It's true that one can do the same by opening the info box of any app to find out whether it can be run in 32-bit mode. And then select the box to force the app to run in 32-bit. That's no doubt about it.
But this little app collects all the information and gives you a nice and user-friendly interface.
The new version even remembers which apps have been selected to run in 32-bit mode.
Just for that reason, I am willing to pay for it.
Moreover, I am impressed by the quick response from the developer regarding suggestions and questions.
Edgarcabrera. I did my payment via Paypal. I didn't find any problem with it.

But I'd like to recommend to the developer to have another payment gateway apart from Paypal, I've tried to pay for this but I can't via Paypal, perhaps google checkout?...

I then went and changed those of my most frequently used apps to 32-bit mode, just to see what happened.
Memory usage has been lowered significantly. Other than that, not much to report about performance, one way or the other, except …
Photoshop CS5 is much snappier on the startup in 32-bit mode. Why? Who knows? Who cares? It now uses less memory and starts faster.
Downside for this developer is that I did this using Get Info and clicking "Run in 32-bit mode" for those apps that offered the option – took me all of a few minutes – so I'm not going to part with my cash.
That's not to say, however, that others might well find this app beneficial, in terms of time savings, or just because they're not 100% sure of what they're doing otherwise. I'm not saying to buy it or not. What I am saying is that the process it is designed to carry out has been of benefit to me, even if I didn't use this app to carry out that process.

In other words, if it's better to run apps in 32-bit mode, then why doesn't Apple do this by default?

SixtyFour will facilitate changing a preference to force an application to open in 32-bit mode.
On newer systems that have plenty memory available, it is better to run an application in 64-bit mode. Applications that are optimized for 64-bit can run faster than their 32-bit counterparts. Applications that open in 64-bit mode can access more memory than their 32-bit counterparts.
SixtyFour will facilitate finding applications that will not open in 64-bit mode.
The best way to run an application depends largely on the memory available to the system, its type and how it is programmed.
