Looks interesting, but what's the helper utility

Hi there, I really like the look of this, did try to install the client on my Mac, but there was a request to install a helper utility which concerned me, just wondering why that would not have been bundled in with the app? Is that ok, or have I got a bogus link? I got raspberry pi's galore, so can pop it on one of them instead, but thought I'd ask.
