You could use MyEtherWallet. It's mainly used for storing your coins. And what's best about it that it's free and it has a app. So you can just download the app on your phone and use that as your wallet. But you can still use the website if you want. Just by downloading a file or saving your private key. Also, If you use the private key method, Be sure not to send it to any one you don't know or trust.
