Ultimately this app did help me find my fitbit, however it really doesnt work very well. The signal goes up and down even when you arent moving, which is very deceptive, it also doesnt get all the way to the strongest even when you are right beside the fitbit which leads you to believe that you arent right beside it. It got me to the right room and after walked around that room for at least ten minutes getting ready to pull my hair out, I remembered where I put my fitbit.
