Coinomi is open source multi coins mobile wallet, you can store both ethereum and bitcoin in it also support many other altcoins and it is more secure than jaxx wallet
Hmm, currently there seems to be Android only...
I have tried. multi-locale is nice, and inputting pass phrase is so easy.
So many coins XD (including which I don't know)
I wish there's its Swift version or cross platform version...
But, great thanks!!
