With hike 2.0 we’ve also refined the user experience and made it far simpler to start a Group Chat or send a 1 to 1 message.
On opening the app, you’ll notice 3 buttons hovering at the bottom of the screen: Group Chat, 1 to 1 Message, Status Update in that order. Simple, functional and yet beautiful.

Step 3: After having added the names of friends, click on Done.
