I use Quiver.app (macOS only). Here’s the original post about it on HN: https://news.ycombinator.com/item?id=11009996
Are you still using it / is it working fine? Around a year ago I switched to obsidian after using quiver for a few years, as it seemed development was stopped and no new bugfixes were coming in.
I am still using it. I was shocked to see an update come in a while ago because I noticed the same thing.
It could use improvements but it is surprisingly stable and bug free. I get the impression the developer treats it as passive income/side project.
