Thanks! We have no plans for a mobile app at this point. We try to make GitLab work really well on mobile screens. There are also native mobile apps created by the community https://about.gitlab.com/applications/ but I'm not sure if they support working offline.

Please don't. We don't need apps for this, a website that works offline is more than enough.

Plus, it's really cross platform, and you don't have to work on 5 different versions of the same app, while not excluding any mobile OS.
