I’ve been looking at smart tiles (http://www.smarttiles.click/), it is possible to use that on a desktop computer?
Absolutely, you just need to use the URL that the SmartTiles dashboard will generate for you and use it in the desktop browser
as @dalec said, it is definitely possible.
I use it on my desktop at work, and on mine at home. I also use it on my laptop with the touchscreen in the kitchen.
The only thing to keep in mind is that your tiles will be laid out slightly differently on a computer than on a tablet (more tiles per row, resulting in less rows being needed). This is also true if looking at it on a phone then a tablet.
