If you use Safari on macOS, you can do anything that you can do in the Instagram app. Well, actually, you can, with a bit of trickery. You can, of course, view Instagram from the desktop or on a tablet, in any browser (check out my photos on Instagram), but you can’t post or manage your photos.
There are apps for iOS and Android, but there isn’t even a tablet version of the app.
It is well known that Instagram only really works on a smartphone.
