WhatsApp Messenger is perhaps the most popular free messaging app available for Android and other devices. This app uses the internet connection on your phone (regardless of its type: EDGE, 2G, 3G, 4G or Wi-Fi, depending on what is available) to allow you get in contact with your friends and family.
You can choose to switch from costly SMS to free WhatsApp in order to send and receive texts, photos, calls, videos, voice messages or documents. It isn’t too hard to figure out why this app is so popular. First, there are no fees whatsoever required to use it. Just make sure that your phone has an internet connection and you can reach your loved ones through calls or messages without paying anything.
WhatsApp Messenger 2.18.306 brings a new thing along. You can now choose an admin for your group conversation and if you wish so, you can only allow him or her to send messages to the group. This will make non-admins able of only reading the messages and if they would like to respond to something they would have to respond privately by choosing to ‘Message admin’.
Moving on, WhatsApp allows you to send all kinds of multimedia formats, from photos and voice messages to documents and videos. WhatsApp Web is a highly praised feature which allows you to connect to your WhatsApp account while being on your computer.
Also, this app doesn’t require you to remember pins and usernames because it works with your phone number. It allows you to remain logged in permanently so that you won’t miss anything important or constantly think about if you are logged in or not. Your contacts are pulled from your phone’s address book so you don’t need to remember any username as you reach them quickly and easily with their phone number.
