New to calorie counting

Hey guys, I'm new to the digital tracking of calories thing. I used to just guesstimate in my head, but right now I'm trying to cut and lose as much body fat as I can(weigh 170 right now wanna get to 150-155). Once I do that I'm gonna start building muscle!

Is there any way to customize settings such as daily protein requirements etc? As a standard because I do weight training I like to consume 1g of protein per pound of bodyweight for example, then I like to meet fat requirements and I don't really care to have any carbs(I just use those to meet daily caloric needs after protein and fat is achieved).

Thanks and hope to benefit from this!
