I have been using hike from last 2 years . Its a nice messanger app . Quite similar to whatsapp but the main USP of this messanger is their funny stickers. I had download so many funny , bollywood, hollywood and many more stickers to express my mood in different occasions with different people. lots of modes are also there like hidden mode is there.
Group chat also there, and many more attractive modes and features are there which I use on daily basis. timeline is also a great feature where I can see the updates of my friend. but only thing which I dislike is I can chat only to my contacts . No scope to add new friends. I like this app simple and sober. very user friendly.
