So yeah, my absolute high score is 21232, what I posted above was the highest of five-ten attempts I made on my computer. I had a few other scores around 10000-15000 but that one took a lot of luck in dice rolls.
Just to confirm, while it is on the app, I checked and the app is exactly the same as the online version.
