The best messaging multimedia app in my view. Whatsapp has become very big game changimg app in social messaging after it has been under facebook. Its very easy to use, size of app is also not so big. Its features like sending location, photos, videos, documents etc. Is very good.
Easy to have all these features under one single app.it has now introduced voice and video calling as well which has made people using it more attracted towards whatsapp. Call quality is also very good. Love using it very helpful for free messaging and calling.
