It doesn't take into account body type, like height
, fat, muscle, etc, or whether you're gaining more weight
in the beginning of the pregnancy and less later or vice versa. I'm 5'5" and before pregnancy was 125. At 37 weeks I now weigh 158. This app told me my weight gain was excessive too, but I've always been very healthy and in good shape. So don't even bother entering in your weight. You know yourself and you know what healthy feels like.
