QASH is an ERC20 token. That means wallets like Exodus and MyEtherWallet can be used to store them. Personally I use a mobile version of MyEtherWallet. It works smooth and got no issues.
I'll share it with you here, cause it's temporarly not available on the PlayStore unfortunately: https://jumpshare.com/v/0vdkxlndOWq5CdTQjzju
Have fun!
