Really good app. User friendly. Fun to use with the amazing stickers. it also includes free hike to hike voice call and video call. After some time you will get used to it and find it better than other messaging apps. There is also an option to hide your chats and it can be accessed only with a 4 digit pin set by the user. You also get an option to avail offers by free coupons of various places sponsored by hike. It compatible with all smartphones. I recommend everyone to use this app and no one will have any complains ever. Really good messaging app.
