Few considerations to keep in mind while selection the right wallet are:
Should support multiple currencies so that all the cryptocurrencies and tokens can be at the same place rather than multiple wallets. Work different wallets it's a hassle to remember different logins and passwords/ private keys.
The wallet should be secure so that your funds are safe and cannot be hacked. Each wallet has a public address and private key ( just like the bank locker which has two keys). The user should always be in control of the private keys.
It is also desirable to have the SWAP functionality built into the wallet. It makes it so much easier for the user to swap between two coins. Else one would need to transfer the currency first to an exchange then buy the other currency and then transfer back to wallet.
Other features to look for in a wallet are multi signature and hierarchical deterministic (HD) implementation.!
PINT wallet by BITFIA LABS a Singapore based company provides the above features. Currently the Android version is available on the playstore and it's only about 4.4MB in size. It currently supports 6 Cryptocurrencies viz. BITCOIN, BITCOIN CASH, ETHER, DASH, LITECOIN and DOGECOIN.
In future the company plans to add more functionality like multi-signature, hardware wallet integration, ICO launcher and P2P.
