Joined MooMoo one month ago and I have been using both the mobile app and desktop application. I would say both platform complements one another well.
MooMoo has done a great job to put some of the heavier duty features onto the Desktop application, e.g Best performing industries, Gain Ranking, Amplitude Ranking, Turnover Ranking, etc. Most importantly I like the fact that I can easily design the dashboard to my liking so that I can see all the information that matters to me at a glance.
Have a look at some of the screens I captured from my Desktop.
