The Flygrip is a small adhesive accessory that attaches to the back of a phone or tablet and uses your middle and ring fingers as a stabilizer with your index finger as a counterweight, enabling true one-handed use of large-screen devices. It also doubles as a kickstand: pull out the back piece, slot it in, and you have a hands-free viewing stand.
On a Galaxy S II with its large display, one-handed operation was difficult at best. The Flygrip solved that problem and also improved grip during two-handed use. One-handed Swype became noticeably easier. The package includes the Flygrip itself, padding for smaller hands, extra adhesive, an alcohol swab, and documentation. Priced at around $30.
