Those apps I have are all free and I don't understand
how their free stuff makes them any money,

I can only guess that the authors just like to give away their work.
And it's not unheard of in other OSs, especially Linux.

Some of them do offer versions that cost $1 that have
extra features. But in every case with what I do, those extra
things aren't worth it. An example is Touchpal, the keyboard I
use. It's free. For extra you get some different color skins
for the keys kind of stuff. I guess that floats some folk's boat,
but I doubt I'd use it if it were free.

I would have difficulty bringing myself to pay $20 to $99 for Windows
software but I don't mind paying a buck occasionally for an app that I
really enjoy. And I tell myself that since I spend several bucks a day
on sodas, why the heck not...
