Abstract: A removable cover for a finger brace comprises a receiving end with an open area for receiving the finger brace within the cover and with rails to slide the cover over the finger brace. A stop bar of the cover acts as a stop for the finger brace. The cover includes a spring-loaded clip arranged across the stop bar and rotatable around a fulcrum. A protrusion/recess pair between the clip and the finger brace is normally engaged with a spring and acts as a catch when the cover is in place over the finger brace. A recess in the cover receives an end of the clip when a user presses the end against the spring force to disengage the protrusion/recess pair.

Abstract: An apparatus that facilitates one-handed use of a mobile device has a finger brace configured to brace a user's finger on each of two opposed sides of the point where it is coupled to a flexible member. The flexible member extends through a hole in the back portion of the mobile device's case and is anchored to an interior surface of the back portion of the case. The flexible member's length is such that two fingers of the user's hand can press against the finger brace to brace the mobile device when the two fingers are between the finger brace and the case.
