WhatsApp Messenger is a cross-platform mobile messaging app which allows you to exchange messages and make phone calls without having to pay for SMS. It Is available for iPhone, BlackBerry, Android, Windows Phone and Nokia.
WhatsApp uses your existing internet data plan you have for email and web browsing, so there is no additional cost to send SMS or call. Users can also create groups, send each other images, video and audio media messages.
WhatsApp is accessible both on your phone and your computer. WhatsApp Web is a computer based extension of the WhatsApp account on your phone. The messages you send and receive are synced between your phone and your computer, and you can see all messages on both devices. Any action you take on the phone will apply to WhatsApp Web and vice versa.

WhatsApp's end-to-end encryption is available when you and the people you message use the latest versions of the app. This means only you and the person you're communicating with can read what is sent, and nobody in between, not even WhatsApp.
You can set your last seen, profile photo and/or status to the following options:
Everyone: Your last seen, profile photo and/or status will be available to all WhatsApp users.
My Contacts: Your last seen, profile photo and/or status will be available to your contacts from your address book only.
Nobody: Your last seen, profile photo and/or status will not be available to anyone.
The WhatsApp Live Location feature allows you to share your real-time location for a specific amount of time with either the participants of a group chat or with just one contact via an individual chat. To use this feature, you need to turn on Location and give WhatsApp location permission in your phone's settings.
You can control whether and how long to share your live location. You can also stop sharing your live location at any time.
This feature is end-to-end encrypted, which means no one can see your live location except the people you shared it with. For more information about Whatsapp’s security, click here.
You can report problematic content by contacting WhatsApp from inside the app.
You can block people on WhatsApp, which means you will no longer receive WhatsApp messages or calls from them.
The first time you receive a message from an unknown number you will be given the option to report the number to WhatsApp as spam directly from the app.
WhatsApp may ban accounts if they believe the account activity is in violation of the Terms of Service.
