I own a MacBook Pro M1 13", and I notice on the Istatistica App that I have a lot of free memory but on section Other, as Free with green color appears less.

As well on Activity memory, I can't see Memory Free.

The Mac OS is just a fresh install.

Does anyone know a solution to this issue?

Sounds like the solution is to find out what Istatistica means by Other. There doesn't seem to be any other issue. (I don't know what you mean by Memory Free in Activity (Monitor?).)

As you can see, free is only 2.5gb, i made an clean install and is the same.

Free now is 1.29gb.

macOS makes use of available memory to optimize system and application performance as it sees fit. It does not leave empty memory just hanging around if it can use it for something, since unused memory is wasted memory.

I don't know why this application you are using calls it "Other", or why the memory readouts differ between it and Activity Monitor.

Is there another way to see tge correct free memory?

You don't need CleanMyMac or other stat menu apps showing about how much free memory is left, as the OS will load as much memory as it can, even if it isn't actively using it all of it at any given moment. What you need to focus on (from time to time) is what the memory pressure shows. If it stays green, you are fine. If it shows yellow or red on a consistent basis and the swap file is consistently greater than zero, you are taxing the system when it comes to RAM usage.

The meanings of "free," "used" and "available" are various (different definitions in different systems and apps) and they overlap, they do not mean what you think they mean.
For example, memory that used but is purgeable is also available.
I suggest ignore the used, free and available readings, they are misleading and not useful.

Instead, use the memory pressure and the amount of swap and compressed memory to get an idea of how much demand there is on the memory.
