Abstract: The first embodiment of the present invention presents a mobile device holder that is comprised of four components: a single finger holder, a single finger tensioner, a base platform; and an adhesive pad. The single finger holder and tensioner are permanently attached to form a first assembly, and the base platform and the adhesive pad are combined to form a second assembly. The adhesive pad has a cover that when removed may be used to attach the second assembly to a mobile handheld device. The first assembly is easily attached to and removed from the second assembly by a user. The first assembly may be rotated 360 degrees relative to the second assembly, and is held snugly in place by the single finger tensioner. Several additional embodiments are presented. One alternate embodiment replaces the single finger holder by a two-finger holder; another embodiment has an accessory that attaches to the handlebars of a stationary bicycle.
