For transparency: I'm a developer of RemNote, and as such, I have been using the product for more than a year now. The UI/UX has improved from barely usable, to a pleasant experience. Our company is really focused on the community, and that will continue to drive our product. In that sense, I really stand behind our company mission. Sure, there's plenty of things to improve, like further UI/UX polish, and a lot of stability improvements. That said, I think the current version is ahead of its competition in terms of gaining and retaining knowledge. That's why I'm giving it 5 stars.
