Cons
Con Hasn't been updated in 2 years.
Con Expensive
The price of $99 is more than many other editors.
Con Sync issue under Linux
The Linux client has a bug that requires the user to click the mouse frequently in order for sync to proceed. This bug has been open for a while.
Con Gargantuan memory footprint
1GB+ of memory for taking notes.
Con Old school interface
Con Bloated
This project is suffering from feature creep and uses a lot of memory for a note-taking app.
Con App Image launches very slowly
On Linux, you can only install via App Image, which take 5+ seconds to launch. I can launch LibreOffice in under two seconds.
Con Sync issues on Windows
No way to change account settings and sync easily corrupted.
Con Weak tag searching
Joplin can currently only search for a single tag at a time. None of the boolean operators (AND, OR, NOT) are available for use in searches. This greatly diminishes the usefulness of tags in Joplin.
Con Can't create tags from the mobile app
