re: Most useful, FREE, and complete health/fitness app?

As many have said, MFP is probably your best bet for a free app. Yes, it is tedious. Yes, when you eat out, it's not easy to get an exact measurement. But a) if it were easy, everyone would be doing it, and b) if you're trying to lose weight, you probably shouldn't be eating out often anyway.

And for people saying it's for women, you clearly are nutrition experts.

I use it to gain weight, and it helps me make sure I've reached my 3,100 calorie goal for the day, as well as my macros.
