The Yimu App helps users to better understand their water quality each time they drink. Via Bluetooth connection, the Yimu water quality detector sends water data to a user's smartphone, allowing users to visualize invisible harmful particles and warning them when they need to change their water filter. Advanced technologies such as automated filter change notifications and long-term water quality data are presented in an interactive and user-friendly interface. The harmonized hardware and software design not only provides the necessary functionality but also offers users a higher quality of life.
