For us, Indians, it lies very next to whatsapp in priority. Yes, an Indian messaging app that has adopted positive features of whatsapp and is going strong. Its unique features includes different stickers for different moods and languages, its option to like profile pictures of your friends as many times as you like and its hide chat option. But one negative I noticed is, when some msg appears in the notifications and you go instantly to the app then that msg doesn't appear in the chat, you have to go back and reopen the chat again to see that particular msg in the chat. Otherwise, its better than any other messaging apps except whatsapp.
