Airbitz's security model is more relevant to Android or to an iOS user who installs sketchy apps or roots his device. I prefer to control my master seed so if my phone is lost or destroyed then I don't have to rely on a developer for access to my wallet. Sure, I can just install Airbitz on a new device, but what if for some reason the app isn't obtainable? It's an unlikely situation but not an impossible one.<br/><br/>As a walkin' around money wallet Airbitz is great. Favorite feature? Local buyers/sellers finder.
