I'm working on a mobile app where I have a profile screen which tracks your stats from previous months on how long you've been meditating for. Should Settings go inside Profile or should I access settings from a different button next to Profile?
I will suggest if you have too much data for the user profile then you have to add a setting button side to the profile, in this case its better to separate the things, so that user can differentiate better.
but in case of you have less date for the user then you can merge them together by adding some icon in interactive way which will define that both(profile settings and general app settings) are under in the same icon
Here i add some of my work, hope it will help you better to work.
