Best app to chat with friends and other contacts. Best part being no marketing adds been used by the app. It’s really annoying to have significant amount of adds when you are doing surfing or using the app.
WhatsApp really thought above and beyond all of them and simply made it free from those. Whats app is the fastest way to share your photos, music, data etc to the friends.
Can create groups and include your friends and share your data. Privacy is the second best feature, people can not search or view the group info of groups which they are not member of. Now they have added whatsapp calling feature, the quality of which is really excellent and helps a lot in saving money by talking via whatsapp.
