About the Client
Annotap is a great android application for people working in an organization to collaborate on documents.
Annotap allows people to invite collaborators to work on documents, add comments and drawings to documents, add new revisions to documents, delete revisions and review archives of previous revisions. Annotap also allows collaborators to take pictures and convert them to PDFs for discussion, as well as to add pictures as comments to ongoing discussions. Finally, push notifications will inform all the people collaborating on a project about any new comments and annotations on the documents.
