I'm Katie... I'm 30 and also new here to this board, going on my 2nd month.
I used to use livestrong, but after a while it got weird and crashed every time I added food..
Which got annoying, lol. So I have mynetdiary now, and I love it. Lots of people like the LoseIt! app too. There are plenty to pick from, and having it right there makes it SO handy!!
I like calorie counting because I can fit anything into my "plan" and I can plan ahead with it.
