Water Quality Mobile App Help

Mayfly card in Water Quality App

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. As of 2020, the app is aligned with the Leaf Pack Network® (LPN).

The app is available for $4.99 for Apple and Android mobile devices. Bulk purchases can be made by organizations with Apple School Manager or Apple Business Manager accounts. There is currently no option on the Google Play Store for volume purchases of the Android version.

App sale revenue is used to make version updates, add new features, and support water education programs.
