About

Flowify AI

Features
Read full description

Flowify AI is a solution that provides a convenient and flexible way to efficiently evaluate lateral flow assays at the laboratory level using your smartphone. It is not dependent on a fixed test cassette design and can be used with any type of lateral flow test (except fluorescence tests). This makes it an ideal solution for test development and incoming quality control. Automatic documentation of measurements makes your life easier and lets you focus on the important things. On the included portal you can track performance over time and detect trends. Comparison with historical data is a breeze. Disclaimer: Flowify AI is not a medical device but can be used in conjunction with one depending on the intended purpose and instructions for use of the respective lateral flow device. The app is intended to be used as lab tooling for development and quality control purposes. The app does not replace professional medical advice. It does not make any diagnosis or treatment recommendations. Always consult a doctor before making a medical decision.
