Smartphone
App
The VisionDrop AI smartphone app contains all your testing needs in one place. With the app you can perform QiFlow tests, calibrate your phone for enhanced accuracy, and view saved test reports to evaluate your water’s quality over time.
Artificial
Intelligence
AI forms the backbone of the app: neural networks enable accurate determination of color changes and a language model interface provides context for test results to users and can guide them through performing a test.
