I like it new name, it was a really smart choice also because of the app version. GDevelop and GDevApp just makes more sense, and also looks and sounds better.
Though what I find really weird is the logo, just looks not right for me the plane text next to the nice “G” logo.
I like the design of the webapp logo better:
I think you should use this, or only the GD from the logo that’s looks even better itself.
Actually the GD in such design reminds me of the symbol of infinite what could also mean in a twisted way “the possibilities are endless” 
Well, just my opinion.
