The Silent Wake Up (SWU) app requires a physical SilentWakeUp wearable device to properly access and manage all features of the app. The app and device communicate user inputted settings and actions via a FCC certified bluetooth transponder. These settings and actions signal when to activate and deactivate the vibrating alarm located within the physical SilentWakeUp device.
The Silent Wake Up (SWU) app sets the intensity level of the various vibration cadences and amplitudes felt by the user.
