This is probably the best news I've gotten all week (yes, it's only Monday, but STILL!)
This Android app, Snowball, is a universal inbox. I don't even want to talk about how many messaging services I have, let alone email accounts, so this sounds like my one way ticket back to sanity.
The app serves as a universal inbox for your many mobile messaging clients, including Facebook Messenger, WhatsApp, SMS, Snapchat, Google Hangouts and more, and appears right on your Android homescreen in a format that resembles the small, circular “Chat Heads” icons introduced by Facebook. (You know those little circles you can toss around your screen? Yeah, those.)
Check out the promo video and if you're as jazzed about it as I am, download it for free on the Google PlayStore! ~ https://play.google.com/store/apps/details?id=com.squanda.swoop.app
