Sharing buttons

On my site I have the following sharing buttons: Facebook, Twitter, Instagram, LinkedIn, tumblr, Pinterest, Pocket, WhatsApp, Skype.

Shall I use the service "Interaction with social network and external platform? In case, in addition to what already requested the following should also be added: Pocket, Pintereste, WhatsApp and Skype.

Or I shall use a different service? Which One?

Thanks

Roberto
