These guys are indeed legit and as mentioned presented at the Texas Bitcoin conference, see here:

In addition to making an IOS wallet they also have a free Chrome wallet (available in the Chrome app store IIRC).  They two cannot sync (as of yet) but I believe that is something they may consider.

I met these guys at TBC and talked to them quite a bit-- they are sincere guys who outside of this do a lot of good in their community as well (educating local KY government, schools, etc).
