There is an app but not mobile wallet. It's called MEWCONNECT which helps in connecting easily to desktop wallet. There are other wallets you can use for ethereum standard tokens like imtoken.
MEWCONNECT works like a "hardware wallet", you'll need it to interface with your fund when using MEW website.
If you won't be buying a hardware wallet like Ledger or Trezor, MEWCONNECT is a good alternative for adding more security to your Eth and Eth tokens.
