The best of Bubble is that it is a simple application to use and that it does not require any type of explanation because its interface is very intuitive and all the menus are very intuitive, the application itself works without any kind of problem and meets my expectations .
Among the different options offered, we can print the diagrams in documents or save the file in different formats such as PNG, JPG, HTML or PDF. It is also possible to share our work through a link generated by the application, this link is read only so it is not possible for other people to edit our diagram.
Another feature that I liked has been that the application has a history in which each action counts, so it is possible to go back and edit or undo according to our needs.
The only negative aspect I found is that it is not a very popular application so finding information about this application on the internet is a bit complicated but luckily it is very easy to understand how the app works so in the end you just learn by yourself.
I recommend buying the license of Bubble since it is not very expensive and unlocks some really useful features, also I suggest that when you finish your work you save it locally to avoid loss of data, I do it by downloading the file in plain text.
Personally at work I use this application to design the flow diagrams of the programming team, this team makes a sketch with the entities to represent and their functions, later I represent these entities in Bubble.us and through a link I can share I work to make sure that everything is well organized.
