Easy UK apps or sites to count carbs and estimate calories

[MoneyJo]

I'm trying to count carbs and wonder if there's a site or app that makes it really easy, even to work out calories from the size of something by looking at photos.
Any recommendations?

I use MyNetDiary.

It's UK products, and you don't need to pay for it. You can log your breakfast, lunch and dinner and if you are unsure on calories you can scan the bar code and it will work it out. It logs your protein and carbs each day.

Wow that sounds just what I'm looking for. Thank you. Is it any good with home made stuff? Making curry later!
