Definitely STAY AWAY from the Lumi wallet. Take a look at the thread I posted like a week ago: https://bitcointalk.org/index.php?topic=4440218
Try out BRD[1] wallet or Copay[2] instead.
EDIT: My bad. Looks like you were looking for a multi-coin wallet and not just a bitcoin wallet. For this case, I'd suggest using Coinomi[1]. It's also a multi-coin wallet.
