xournalpp
Xournal++ is a handwriting notetaking software with PDF annotation support. Written in C++ with GTK3, supporting Linux (e.g. Ubuntu, Debian, Arch, SUSE), macOS and Windows 10. Supports pen input from devices such as Wacom Tablets.
I tried a whole bunch of the these apps, and I decided that Xournal++ [1] is better than Rnote for note taking. However, I have used Openboard [2] for teaching online since 2020.
I agree that Rnote's smoothing is better, but it's tool selection UX is terrible. There are three different bars (top, bottom, and side), and you often need to move your mouse/hand to all of them across the screen in order to select the right tool. In Xournal++ I can put everything on the top bar.
Xournal++ has it's own problems. Pasting an image always makes it so big, that resizing to the correct size is difficult. It also doesn't have a laser pointer, which is why I can't use it for teaching. Creating a new document with the correct template is also painful.
Honestly, in another life, I would write a decent note-taking app.

Project mention: Show HN: Open Scanner, an open-source document scanning app for iPhone | news.ycombinator.com | 2024-09-17
For Android I recommend "OSS Document Scanner" it is just as good as MS Lens and CamScanner in my experience.
