I am using hike messenger from more than 3 years. Although I use Hike Messenger as my secondary messenger to chat with my very close friends. Primary no doubt is whatsapp. The reason not to using hike as primary messenger is only its low popularity. Majority of peoples dont use Hike as they only use whatsapp. But I love using Hike Messenger especially when I am chatting with my dear ones because it is not just a chat. It is an ultimate fun.
In every friendship, we dont have enough things to share everytime. Due to which we get bored chatting with our friends. But Hike contains a huge number of funny stickers, using these in our chats we never get bored and it is a lot of fun. If you are also suffering from boredom chats even with your very close friends then I suggest you to use Hike Messenger. And yes, this messenger is perfect for couples. ; -)
