Abstract: A collapsible ergonomic accessory for attachment to a handheld electronic device, comprising a mountable base, an adhesive element affixed to an underside of said base, a support stand pivotally connected to said mountable base by a hinge element, and an ergonomic brace element at a distal end of said support stand. The ergonomic brace element defines a semi-circular arch configured to engage with a user’s finger. The adhesive element couples said mountable base to a rear surface of a handheld electronic device. The accessory has a concentric geometry of the collapsible ergonomic accessory, wherein the components of the accessory are nested into a substantially flat form factor. The brace element rotates inward and outward from the top of the support stand, which may be a ring.
