In addition to the spreadsheet, I'm going to provide what should be a phone-friendly web page. I've got a small site hosted by a Raspberry Pi that I use for keeping track of my game nights and murder parties. I've added a page for the current standings.
Your browser will warn you that it is not a secure site. The server will automatically update its local copy of the medal counts for each country every 15 minutes. Additionally, the page will auto refresh its display (our standings) every 15 minutes based on the local copy of the medal counts. Note that these two updates are asynchronous. The medal count updates will happen four times per hour on the quarter hour. The page updates will be in fifteen minute intervals based on when you pull up the page.
It's a simple, clean display that will just show the standings. The URL is:
http://pinkmeeple.ddns.net:8080/tokyo
If you use this URL, you won't need to log in. If you try to get to other pages on the site, it will ask you to log in, but should only allow access to this page. The username/password for this page (if you find you need it - you shouldn't) is tokyo/a2k.
You can go there now if you want. It, as well as the spreadsheet, is currently displaying standings based on 2021 predictions and 2016 results per wikipedia.
