I am looking for some notetaking software that has a tree structure in the management of notes and folders. That is, I look for a software that can create multiple notes within a database file. Where possible, the use of the cloud is not required, but the notes can be synchronized, in case I need it in the future.
Also, if possible, recommend a notetaking app that can synchronize with Android offline or online.
Which notetaking software do you recommend?
