A growing directory of noteworthy altmetrics apps:


ImpactStory thumbnailImpactStory is a Web-based application that makes it easy to track the impact of a wide range of research artifacts (such as papers, datasets, slides, research code). The system aggregates impact data from many sources, from Mendeley to GitHub to Twitter and more, and displays it in a single, permalinked report.


ReaderMeter-thumbReaderMeter is a mashup visualizing author-level and article-level statistics based on the consumption of scientific content by a large population of readers. Readership data is obtained via the Mendeley API. Reports are available both as HTML and in a machine-readable version as JSON and are released under a CC-BY-SA 3.0 license.


ScienceCard-thumbScienceCard is a website that automatically collects metrics (citations, download counts, altmetrics) for a particular researcher. All the researcher has to do is provide a unique author identifier such as AuthorClaim or Microsoft Academic Search ID.

PLoS Impact Explorer

PaperCritic-thumbPaperCritic offers researchers a way of monitoring all types of feedback about their scientific work, as well as allows everyone to easily review the work of others, in a fully open and transparent environment.


PaperCritic-thumbCrowdoMeter is a web service that displays tweets linking to scientific articles, and allows users to add semantic information. CrowdoMeter uses a subset of the Citation Typing Ontology (CiTO), an ontology for the characterization of citations, both factually and rhetorically. The results of this crowdsourcing effort are displayed in real-time.
