In my profession of speech-language pathology, I thought this would be an incredibly worthwhile and convenient app (nearly instant availability of signs vs. lugging a signing dictionary around & stopping to look up unfamiliar signs). This was actually one of my first apps purchased and to date (months & months later), at least 50 - 75% of conmonly occurring signs for which Ive searched have been fingerspelling! For an app developed with input from fluent signers, I expect to find signs for the words I search. I must say, though, that the avatar and different views available ARE outstanding!
