Swimer installs as a standalone application: its own home-screen icon and opens as an app, with no browser bar.
On Android (Chrome / Edge):
Don't use "Add to Home Screen": that only creates a browser shortcut, not a standalone app.
If "Install app" doesn't appear, browse Swimer and interact with the page for a few seconds: the browser requires minimal usage before offering real installation.
