WhatsApp Messenger is a popular, free and secure messaging app available for iPhone and other smartphones.
WhatsApp uses your phone's Internet connection (4G/3G/2G/EDGE or Wi-Fi, as available) to let you message and call friends and family.
WhatsApp has recently been updated to support iOS 10. Here's just a few of the new features introduced in this release:
- Ask Siri to send WhatsApp messages or place WhatsApp calls
- Answer WhatsApp calls right from your lock screen, just like a standard phone call
- A new Widget lets you quickly jump to a recent chat or see which chats have unread messages
