Note: This app only works for carers of a PanPan watch wearer. PanPan watch is an SOS device designed to support seniors’ independent living. Telecare providers can use it to monitor and assist seniors in case of an emergency wherever this may happen. It detects falls, location and wandering behaviour, and its single button can connect the wearer to the telecare provider for immediate help. We've developed this app to show relatives basic activity and location of a PanPan’s wearer.
