That's only an app, even without Dogecoin Wallet in iOS, $DOGE coin owners still can pay with another way such as web wallet, android app etc.
This news is absolutely not important to publish, does this news only aim to spread general awareness about the development of Dogecoin (DOGE) that is happening so that people will buy it? I don't think so, the period of Dogecoin is over, I highly recommend not holding Dogecoin for a long time, because this coin is different from Bitcoin, Dogecoin has no supply limit.
Ethereum? Of course Ethereum is different from Dogecoin even though they both have an unlimited supply, Ethereum has a very clear utility.
