After 10 years using SimpleNote I think I'm going to switch to StandardNotes. The most recent update to SimpleNote has made the editing experience really bad. While typing it will randomly jump to different notes, sometimes completely messing them up in the process.
SimpleNote appears to have no business model aside from being funded by Automattic, which I'm always wary of. StandardNotes has the benefit of open-source, encryption, and a business model.
