String theory is trying to be relevant to fundamental physics. Basically, it argues that particles, instead of being point-like objects, are really small 1-dimensional objects. This helps avoid some of the problems in particle physics, where the point-like nature of particles leads to "infinities" in the calculations. With the particles being little strings, the calculations do not have so many singularities leading to infinities. Another aim of string theories is that they try to unify gravity with the other forces: electricity, magnetism, nuclear strong and nuclear weak forces.
The real question is, is "string theory" really relevant? There's been a lot of work on string theory in the past few decades by lots of smart people. There's lots of versions of string theory. But so far, there have been few real benefits of string theory. It hasn't really explained anything new, and it hasn't really allowed the calculation of anything we weren't able to calculate before. So the relationship between string theory and experimental reality is tenuous at best.

If string theory were to lead to a ToE, I would think every branch of science would be affected. But mostly particle physics, I guess.

Particle physics. . . and belly button lint studies too.
Seriously though, an understanding of fundamental particles is crucial to understanding the very early (pre-inflationary) universe, so it has relevance to cosmology too.

Probably physics, but its so weird that it could be metaphysics or supernatural.
