In this article I’ve tried to list all the existing clients for Lync (also the ones that are not effectively installed on a device like Web App).

With a Lync client you are able to connect to Lync and use features such as enhanced presence and contact information, extended voice and calling features, and rich meeting and collaboration capabilities.

Not all the options are available on all the platforms so, first of all, a link to the comparison matrix from Microsoft (comparison matrix for Lync clients features)
