Abstract: A smart device accessory includes a planar support, a neck and a swivel and pivot joint. The neck extends in the length direction between a first neck end and a second neck end at the first support end, the neck having a neck width transverse the length direction less than the support width, curved shoulders between the first support end and the second neck end transitioning from the support width to the neck width. The swivel and pivot joint has a hub pivotably connected to the first neck end such that the neck and planar support are pivotable and rotatable relative thereto. Various bases can connect the accessory to the smart device. The accessory can be incorporated into magnetic mount arrangements and device locator systems.
