I have always used Lose It. It has a lot of great features and is easy to use. It also does not tell you that you are eating too little, which I really like. I don't need a nanny, just a way to track my food and exercise.
I just noticed the changes on the mobile app today. I really don't like the screen that breaks down the total calories, protein, carbs, etc. That was my go to screen to check on my protein intake for the day.
