Yeah, it does work but it doesn't collapse/resize for mobile devices. You have to zoom move it around etc to see things. I use it on my phone as well, but would love to see it formatted for mobile.
I have been thinking about making some sort of cross platform Steem analytics application myself. If I could only find the time!
Tell me about it. Time is the enemy.
As far as resizing goes, it should be automatically and dynamically formatted for any phone as this is set when making the website or app.
It may be something to do with your settings on your phone or maybe it's time to get a bigger phone. 😁
It is pretty small to read on a phone but we do have that zoom facility.
