Hi my name is Tony..!! No idea how this thing works, yet

I've been using the app for the last 6 months and I use to use it back in 2010 and saw improvements which is why I'm using it now. I've always used it to keep track of the calories and make sure I'm eating enough as I find it hard to put weight on... With this app I can see how many calories I'm putting on and whether it's mostly carbs, protein or fat as well as vitamins etc.
I think it's good and helps motivate me a little. It's also only in the last month that I have been looking at the community on here and seeing how I can meet people who can also motivate me and possibly meet locally
