Water Quality Mobile App Help

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. Apple’s Volume Purchase Plan, available to educational institutions and businesses, allows bulk purchases of the app. There is currently no option on the Google Play Store for volume purchases of the Android version of the app.

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

If you need to purchase multiple copies of the Water Quality app to distribute to classes or groups, you can do this through Apple’s Volume Purchase Plan (VPP). The VPP is separate from the Apple App Store and is available to educational institutions and businesses here. You will need to connect to an existing Apple School Manager or Apple Business Manager account or create a new one. Through the VPP:

  • Purchases can be paid via purchase order.
  • Purchases aren’t tied to specific Apple IDs.
  • Purchases can be moved between devices and/or users.
  • When you purchase content for your school or business, you can distribute your purchase directly to your users using the User Assignment and Device Assignment features of managed distribution, or the redemption codes feature of Apple Business Manager.
