The best thing about this app it's that you can send files to anyone in your contact list without having them download an application or software! I have used other messenger apps but they don't allow me to share my contacts with others so i had no choice than downloading another one which was not as good at sending pictures too!! This has solved everything! There isn’t anything bad because of its simplicity; if there were any problems we could easily solve those ourselves by using their support team who will help us out instantly!
