Drausible shows your Plausible Analytics stats on your Android phone. Add the server, whether that
is plausible.io cloud or a Community Edition one you run yourself on your hardware, add the sites
you want to observe, and you get the dashboard without opening a browser.

No account, you issue the API key which you feed to the application.
You need to add sites manually, as site listing is not a part of Community Edition API.

Stats per site:

Visitors, visits, pageviews, views per visit, bounce rate and average visit duration
Visitors over time chart, bucketed by the hour when you look at a single day
Top pages, sources, countries, devices with a switch between type, browser and OS
How many visitors are on the site right now, kept up to date while the screen is open

A few things that matter if you self-host:

Servers too old for the v2 stats API will fall back to v1 automatically
Plain HTTP works too, as instances on a home network often run without TLS
Each server can go through its own SOCKS5 proxy, so a .onion address works with Orbot
