It works best on a phone / tablet but on a desktop it’s fine too once you switch to compact mode.
It can be installed as a PWA.
There are also lots of themes you can try at https://piefed.social/user/settings. Here are some screenshots of them - https://join.piefed.social/screenshots/
I love Blorp and it’s my default interface/Piefed app on mobile. It looks very polished and thought out.
That said, I am not happy with typography that modifies contrast for emphasis. It works alright in dim conditions and / or dark mode, but in bright environments the low contrast portions of text become completely invisible, not just unreadable. That’s not Blorp in particular, it seems to be a design trend ATM.
