Proper hand-washing practices are promoted by bodies such as the WHO and the Center for Disease Control (CDC) as a primary source of protection against micro-organism-related disease, that caused by Covid-19 included. To this end, Samsung's Research Institute-Bangalore (SRI-B) UX and wearable teams have produced the Hand Wash app for Tizen OS.
This app helps the user make sure they maintain a healthy hand-washing routine through a pattern of regular reminders. It can also track the number of hand-washes completed per day, while assessing how well the user performs this activity using a given watch's sensors.
This ability to inform and refine hand-washing technique incorporates the latest CDC criteria to do the same (the '20-second' rule, for example). This app is now available to download on all Galaxy-series watches. However, XDA contributors have reported that it also works on other Samsung smartwatch lines such as those of the Gear variety.
