lock by location

[nursemm05]

for the life of me I can't find what I am looking for. Perhaps it doesn't exist. I want a password lock that is enabled by my location. I want it to be able to just slide to unlock when I am at home, but require a password or gesture when I am at work. I have searched for lock by location, password by location, and lock by gps but can't find what I am looking for. Anyone have any suggestions? I have searched in the android market and the appbrain market for days now!! I don't mind paying a reasonable fee as long as I know it works. I'd rather it at least have a trial so I can test it. please someone help!! you guys are so much better at this than I am! thanks!!
