For Android, you can use trilium as a PWA currently, I do that and it's not bad at all, but offline isn't supported yet. I would say that the UX through the PWA isn't worse than that of Obsidian. If offline on your phone is a requirement, you should be able to run trilium server there (haven't tried): https://github.com/Nriver/awesome-trilium#-android

There is managed hosting too, at a very fair price I'd say (compared to the alternatives): https://trilium.cc/
