I didn't read about Ethos, and I'm new here, so i don't know a lot. But as far as i've seen regarding the multi-coin wallet, Bread might be a competitor. Their wallet is released already on Google Play, i've tried it, but so far it's limited, still in development. I think it has potential though, I considered investing in it. I'll take a look at Ethos too, at first glance it sounds like a broader approach.
