The FSOS (Female Single Operating System) is pretty much the same, it has the Husband 1.0 app. They don't run on the same processor type and it's a little different in operation but the logic is compatible and it comes with apps like Boyfriend 2007. Wouldn't recommend the Boyfriend app while running Husband 1.0.
Of course the FSOS is a little more complex and comes with the basic (and sometimes, confusingly and randomly the Advanced Version) Flirting app as standard.
