The essential cross-platform messaging app
WhatsApp is a cross-platform instant messaging client that has quickly found a fanbase among those that wanted the joy of certain BBM features elsewhere. WhatsApp has activity indicators so users can tell when others have been active, if they’ve received messages, and when they’re typing replies. There’s full support for emoticons and organizing users into groups.
The favorites section is automatically populated by contacts identified on your device by phone number to be WhatsApp users. You can set your own user status to anything you like (though there are plenty of helpful presets immediately available). You can share pictures, videos,voice notes, contacts, and locations, to boot. If Google Talk and the other official instant messaging clients don’t do it for you, WhatsApp is a good second stop.
