Kik

Kik Messenger is a app that lets you easily communicate with all your friends and contacts, sending them text messages, pictures, and chatting with them in real time.

The app has some interesting features, such as the notification system, that lets you know when one of your messages has been sent, delivered, and most importantly, read.

As with most similar apps, you can create group chats with your friends, which is perfect for organizing group events. You can be in as many groups as you like, and each of these groups can have dozens of users.

One of the features that make Kik Messenger unique is its integrated web browser. This lets you open any hyperlink that you receive without leaving the app, which can save you lots of time.

Kik Messenger is an interesting alternative to giants like WhatsApp or LINE. It has similar features and a clean and simple interface. If there's any downside, it would probably be the registration process, which can be a little tedious compared to other applications.
