I’ve tried WhatsApp, GroupMe, Kik, Google Voice, LINE, Trillian, and basically every other messaging app you can think of — I’ve even tried using Skype as an IM service, because at least my parents know what Skype is. I’d given up on finding an app that had all three things I need: cross-platform, useful online and off, and accessible enough that I could convince everyone I know to use it. But Google’s new Hangouts app is all that and more.
Strange ! Even the notifications number doesn’t update correctly !
