|What is the accuracy of the app?||The accuracy depends on the accuracy of the test strips. Test strips for nitrate give an indicative measurement. In our tests, we've found an accuracy of ~30%, while conventional laboratory measurements have an accuracy around 10%. See also the Accuracy page.|
|What does it cost?||~0.50 EUR per measurement. Check the getting started page for an order form.|
|What is your business model?||Like all Deltares software, the app is free ('dare to share'). We're mainly interested in finding new projects to work on the next developments for the app, which will then become available for the entire user community. Organizations with specific requests (e.g. other parameters, an own private web viewer) are encouraged to contact us.|
