The popular Snapchat app has been updated [iTunes], adding one-to-one instant messaging and live video calls …

Swipe right on a friend’s name in your Snapchat inbox to start chatting. When you leave the chat screen, messages viewed by both you and your friend will be cleared – but either of you can always tap or screenshot to save anything you’d like to keep (addresses, to-do lists, etc.)!

We let you know when a friend is here in your chat so that you can give each other your full attention. And if you’re both here, simply press and hold to share live video – and chat face-to-face!

The app added phone number opt-out in January, to address privacy concerns associated with the Find Friend function. An earlier update introduced photo filters, as well as allowing more ‘best friends.’

Snapchat is designed around the concept of sharing brief moments with friends, with photos and videos disappearing after they have been viewed. The app is a free download from iTunes.
