This is what they said, they are well aware of the porting process and it appears they have looked in to it by giving it some serious thought, but it just may not be feasable for them to develop natively which I guess is fair enough from their point of view.

Therefore, the MyFitnessPal application, unfortunately will not be available for use with the Blackberry 10.
However, our program is always available via our website at Free Calorie Counter, Diet & Exercise Journal | MyFitnessPal.com
