The best for me is Coinomi It has the shapeshift.io exchange built in and just works flawlessly. You get a clear overview of all your balances, and Coinomi combines this balance so you can see exactly how much your crypto is worth. Coinomi is open source, stores your private keys locally and encrypts them. This makes it a really safe wallet.
