Say no to pins and usernames: Why even bother having to remember yet another PIN or username? WhatsApp works with your phone number, just like SMS would, and integrates flawlessly with your existing phone address book.

Chat with your friends all over the world as long as they have WhatsApp Messenger installed and avoid those pesky international SMS costs.

No international charges: Just like there is no added cost to send an international email, there is no cost to send WhatsApp messages internationally.

Personal: Set a profile photo which will be shown to all your contacts.

Add or Remove group participants, change group subject and set a group icon.

Group Chat: Enjoy group conversations with your contacts.

Multimedia: Send Video, Images, and Voice notes to your friends and contacts.

Send a million messages a day to your friends for free! WhatsApp uses your Internet connection: 3G/EDGE or Wi-Fi when available.

No hidden costs: Once you and your friends download the application, you can use it to chat as much as you want.

You can also download the latest WhatsApp Final for Desktop here. WhatsApp is available for mobile platforms Android and iPhone / iOS. Just like WhatsApp Web, the new desktop app lets you message with friends and family while your phone stays in your pocket. Upon downloading and opening the app, scan the QR code using the WhatsApp app on your phone (look for WhatsApp Web menu under Settings).

Because the app runs natively on your desktop, you'll have support for native desktop notifications, better keyboard shortcuts, and more. The desktop app is available for Windows 8, Windows 10 and macOS 10.9 or higher, and is synced with WhatsApp on your mobile device.

WhatsApp desktop app gives you a new way to stay in touch anytime and anywhere - whether on your phone or computer at home or work.
