What value does QKSMS add that Hangouts does not? "It looks better" is a very valid answer, but honestly after reading the Google Play page, I'm still not sure. From reading the description in the Play Store, here's where I believe QKSMS differs from Hangouts: * More visual customization * Offers a mysterious QKReply feature (screenshot seems to suggest this is a special dialog for replying to incoming messages) * MMS may sometimes be more difficult to set up
