I'm looking for (preferably open-source) solution, replacing Evernote application and service. Main reasons of the move are terrible usability, bugs and privacy concerns. My preferences are simple.
– GUI: Markdown is preferred but not required format (I understand it's not an option for non-tech people, which would cut the possible application audience), hierarchical structure of notebooks and notes, tags.
– Sync options: using existing cloud service (preferred) or self-hosted solution. Reasonable privacy and security options.
– Stable release, not unusable beta.
– Possibility to import existing notes from Evernote (enex format)
– Applications for Mac, Windows, Android and iOS
