technology and weight loss

so tech is great. i use a polar heart rate monitor, manage my blood pressure and my weight and fat%. so i am not a great tracker though. i use it to record my sport sessions but i hate tracking my food. but ..... then i found my fitness pal
unlike other apps i can just add the calories and polar heart rate kcal rate and then its done.
So if you havent tried it i suggest that you do. its even converted die-hard avoiders such as me :)
