For my application there's no intrinsic need for "social" or "sharing" features. It's supposed to be a productivity application where each user does his/her own thing. The target user are mostly non-technical people which probably will not have the need for have it on more than one device, so "sync" of data between devices may not be a relevant for them.. If I go the desktop way, I will probably use Qt (PyQt5) so there's some degree of freedom for cross-platform.
