It's called cron-o-meter. The version I've got I downloaded from here: It was recommended to me by a friend of mine who is really into weights.
You may find it a bit frustrating at first because you have to enter some of your own values for foods and things (it's set up from a US food database), but once you enter food it stays there. It's also a lot more complicated than I make it out to be but I've disabled most of it because I don't know what to do with it. (If you get it to predict calories for you, be aware it's going to give you maintenance not weight loss calories, but you can enter those numbers, as well as adjusting macros, yourself. Also I don't know if it does kilojoules, which may be a pain for you)
