> Wait, what?? Why on earth would you use an app with ads for health devices?!?

GP said they want to _write_ a web app that talks to health devices. And that they like the web platform because it's easy to block ads shown to you by other web apps.

I will add that it's also easier to detect/block tracking. Browsers such as Firefox even try to do this for you these days. And to generally examine what the app is doing (e.g. by running it in JS debugger).

Yes, paid apps usually (but not always) remove ads. They keep the telemetry, though.
