Joplin: An user-friendly note-taking and to-do application with sync capabilities

Joplin is an Electron-based piece of software that enables you to create notes and to-do lists, as well as manage them. The program is open-source and there are versions for all popular platforms including Windows, Linux, Mac OS, and Android.

Joplin includes synchronization functionality so you can sync all your notes and to-do lists between multiple devices and other targets like Microsoft OneDrive.

You can organize notes and to-do lists into notebooks, and also sort them using tags to make them easily searchable. The program allows you to import notes from Evernote using .enex files and the imported resources including images, attachments and your notes' metadata such as geolocation, time of creation, and time of last modification will remain unaltered.

If you've been searching for a free cross-platform application that lets you create and manage complex notes as well as basic to-do lists in offline mode and provides synchronization options, Joplin is an excellent solution.
