This little app shows a lot of promise. It's great for sketching quick UML class diagrams with a minimum of effort.

There are two areas where it badly needs improvement.

First, it does a very poor job of following basic macOS file management conventions. For example, if you double click one of its documents, the Finder launches the app, but the app refuses to open the doccument. The only wan to open an existing document is from the File menu within the app.

The second area where this app badly needs improvement is in the routing algorithm for class associations. The app sometimes routes these in crazy ways and the user has no way to nudge the lines into a more sensible position.

Despite these two flaws, this is still a useful tool and is worth the 99 cents price.

I hope the author continues to improve this very nice little app and addresses the issues I noted above.

Hi K. Rande,
Thank you very much for your feedback and sorry for the inconvenience regarding the file opening behavior, I will investigate the issue asap and try my best to fix it in the next release.
The next version (1.6) will also provide an update to the routing algorithm, along with custom anchor points to adjust the routing and additional docking ports.
If you encounter any other issues, please don't hesitate to contact me at contact@umlboard.com.
Best regards,

This is a clever little app that knows what it shoud focus on - class diagrams and explanatory text around those diagrams. you can almost treat it a bit like a word processor with embedded diagrams, i find i can construct nice little design explanations with it.

It would be nice if it did multi-page or something equivalent, so i could hold a larger model, but in it's current form it's very tight and useful so it's hard to complain!

Hi KingPurply,
Thank you very much for your review. I'm happy to hear that you like the app!
Support for multiple pages/diagrams is definitely an important feature. It's already in the backlog, but it might take a bit until it's available.
If you have any additional feature ideas or encounter any issues, please don't hesitate to contact me. Thanks!
Best regards,
Patric

I've played with lots of UML tools, and this one really stands out. It's both simple and fun - this makes it a tool I want to come back to, where I can just focus on accomplishing what I want. Really appreciated how fast it was to lay out and manipulate designs.

Hi Happy-Days619,
Thanks a lot for your review, I'm happy to hear that you like the UI, but I'm also very sorry that you weren't able to save your file.
There seems to be a weird bug in Version 1.8.2 that affected some users when saving a file, but I wasn't yet able to reproduce it.
If you don't mind, could you please contact me at contact@umlboard.com and I will do my best to fix the issue as soon as possible.
Thank you in advance and best regards,
Patric
