I do, mostly. Also anticipated there'd be at least one mobile/desktop app dev who would swoop in to say it's important there too and I agree! It's just so common to have two servers to deploy to, and as soon as you do, you aren't going to repeat manual steps to deploy your software on them. I guess in that sense app stores are sort of like CI for apps :-P

But indeed, especially on mobile where you need to have releases go through external validation, CI/CD can save you a lot of time.
