WhatsApp can be downloaded from the website WhatsApp.com. The program is available for iPhone, Android, BlackBerry, Nokia and Windows phones. Downloads for iPhone and Windows redirect to the iTunes App Store and Windows Marketplace respectively, but other platforms are available directly through the site.
WhatsApp is a messaging program that lets users send text, picture, video and audio messages across platforms without the user having to pay for text messages. Users can download and save images and video from the app on their phone or on another device. Sent and received messages are stored in the cloud, letting users access old conversations without keeping a local copy.
