Maybe mermaid fits your use case?

I use OneCalendar, it works with a lot of email/calendar hosts, looks good, and is very responsive.

Alternatively, Thunderbird has a calendar feature built-in.

(Edit) failed to see which community this was, OneCalendar is sadly not open source.

Ooh that looks great! Thanks for sharing, I’ll check it out!

I use qBitController to check my torrent status, it works quite well for my needs. If you’re on Android you could try it out…

I think you mean this one?
