Hi all,
I have also been using My Fitness Pal for calculating the food I eat, I don't think there is an easier app to use with an existing user-generate food library as large as MyFitnessPal.
HOWEVER!
With regard to calculating energy expenditure and your target energy intake, I've found there to be huge variances in the quality of the calculators, particularly since most calculators don't tell you what data sets they are using to calculate your energy expenditure nor do they allow you get the most ACCURATE measurements (which can only be obtained when you have accurate body composition measurements)
There is only 1 calculator I am aware of that provides you with all of this functionality but also provides you with the option to calculate using your Max Fat Metabolism (this comes from a study where the researchers found the daily limit a person's fat stores can provide in terms of energy).
The calculator can be found here:

Lots of Love
