Next time you talk with your loved one or friends, don't just call or text, send attention request to notify them that you need their attention.
App provides option for two types of requests : For loved one and For friends.
The other user will get notified prior to your actual conversation, so you can also make sure that they are available to have a conversation with you.
Maybe you are getting bored, but sending a miss call seems a little bit old fashioned.

You can also add a text message with your attention request to let other person know what you are up to.
