I’ve been using it for about 10 months.

I always keep boardmix open while working on my computer, and my main usage is to insert daily information into it.
There have been no cases of data loss or server inaccessibility so far.
Overall, it’s been relatively stable to use.

If I had to point out a flaw, it’s that uploading images or videos sometimes results in errors. Even files around 10MB can cause errors, so I’d like to see improvements in this area.

There are minor bugs here and there, but with frequent software updates, I think it’s a good app.
Last year, I couldn't use it properly with a Chromebook, but now it works.

I also purchased Pixso, but if the main purpose is a whiteboard, boardmix is the better option.
The whiteboard feature in Pixso is more of a basic tool.
