counting calories — Dutch (Netherlands)

counting calories

I often see different outcomes in calories during exercise. Who knows a good app that keeps it accurate. I use Endomondo myself, but if I look at MFP and someone does the same, the person consumes far fewer calories. I understand that it works differently for men and women and also when someone has more weight than the other. So I do not mean that. An app that keeps well if I have entered my details correctly.
Thanks
