For my application there&#x27;s no intrinsic need for &quot;social&quot; or &quot;sharing&quot; features. It&#x27;s supposed to be a productivity application where each user does his&#x2F;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 &quot;sync&quot; of data between devices may not be a relevant for them..<p>If I go the desktop way, I will probably use Qt (PyQt5) so there&#x27;s some degree of freedom for cross-platform.
