samsung gear 2/MFP integration

Dear all,

after reading following topic
myfitnesspal.desk.com/customer/portal/articles/1373106-how-does-the-samsung-galaxy-gear-smart-watch-work-with-myfitnesspal-

I went and bought gear 2 since I lose my fitbit one (second times) due to it very small item, so I thought I will go and buy something can not be easy lost, I was away from gear due to it's not integrated with MFP, I actually changed my nikefuel due to this, and when I read the above topic I bought gear 2, but I stuck, I cant make it work with MFP, I follow the steps mention, there is no "features" available on "my apps" and can't find "myfitnesspal" on samsung app.

second issue I notice that the pedmeter on gear 2, away from accurate compare to fitbit.

my samsung S4 (S health) saying I walk 9000 while gear 2 saying 6000, there are 30% different !!!!!

I bought gear 2 so I can use the HR monitor while walking/exercising so it get better accurate data while I see it's completely wrong result, maybe I'm doing something wrong I dont know,

for now can someone help me with liking both applications as the above topic mention ?

thanks
