The most popular and safest of the purses supporting ERC-20 tokens is MyEtherWallet. Long-term stable, I have no problem with this web wallet. For tokens I strongly recommend MEW. If you plan to participate in an ICO in the future, you may also need such a wallet supporting the ERC-20 tokens. But if you decide on an Android wallet, I can still recommend https://www.infinitowallet.io/ - support for ERC20 and NEP-5 tokens.
