About the Tool

The Water Quality mobile app is a water-monitoring data-collection and learning tool designed for use by educators and their students, citizen scientists, and researchers. The app helps users log and share data they collect in the field, interpret the data through learning pop-ups, and export it to create databases.

Available for Apple (iPhone, iPad, and iPod Touch) and Android (phones and tablets) mobile devices, this app includes data entry, identification, and learning features about chemical (e.g. dissolved oxygen, E. coli, pH, nitrate, turbidity), physical (e.g. water temperature, turbidity), and biological (a digital field guide to macroinvertebrates) water-quality parameters.
