Altmetric is a company that provides tools that allow researchers to monitor and measure conversations about their publications and those of their peers. The distinctive Altmetric "donut" combines a numerical attention score with a ring of colors that represent the types of attention received.
Impactstory is a tool that allows you to promote, manage, and share your research and scholarship. Add materials to your profile using your ORCID researcher ID, Google Scholar Profile, DOIs, and PubMed IDs. Impactstory gathers altmetrics for these materials from many sources. You can receive a weekly email report of "new research impacts" (example here) and use your Impactstory profile as an alternative to a static online CV (example profile here). Sign up with your Twitter account or ORCID researcher ID.
