The Kick Counter Wristband by the Count the Kicks charity is a low-tech wearable that challenges expecting mothers to keep track of baby kicking.
The numbered band is designed to track episodes of movement, so that a pregnant woman can begin to get a sense of what is normal and what is not. For instance, Count the Kicks describes that "10 minutes of constant movement would be one episode." After using the band for a number of days, if a woman monitors fewer kicks than normal and finds this concerning, the idea is that this information could be then taken to a midwife or doctor.
This device seems deceptively simple, but the band empowers expecting mothers to get in tune with their own bodies and babies, rather than relying on insights from apps and automated devices.
