Body Fat % calculators

Does anyone use the Omarion body fat calculator because recently mine has been all over the place and in my opinion for no good reason. For example I used my Omarion yesterday and it said that I was like 16.4 % body fat or roughly 28.5 pounds of body fat. Today I used it and first it said 17% I knew it was impossible for me to have gained half a pound of fat in a day so I used it again. Now it read 16.6 which is still a significant gain... What does everyone else use and does anyone else have this problem?
