Fitness apps that are good for omad and other diets

Do you guys know of any good fitness apps that is good for omad and any diet? I remember using a service called lose it. It helped count calories, your intake and I believe they also helped you with fitness.

Are there any other good apps worth checking out?
These are some that I know of:

Calorie counter by lose it
Google fit
Beachbody (I think they got one)
I'm going to check out Google Fit. The others don't quite appeal to me. I used to use a step counter app a few years back, but forget what it was called.
