It's a free and open-source app that works all major platforms out there such as Windows, macOS, and Linux, as well as iOS and Android (and it provides a terminal client as well). Joplin can double down as both a note-taking app and a to-do list utility. Be that as it may, Joplin is unique thanks to its incredible feature set, extensibility options, and remarkable general flexibility. Joplin is not the first, nor the last note-taking app to come up over the years and have web technologies at its core.
