What infuriates me is that often these "services" could be easily served through a simple web app. Provide a link or a QR code, let folks open the URL wherever they like, and stop bitching. But no, everybody requires a freaking native app now because it's the best way of locking people in and scooping up data even when their browser is closed.
The EU needs to forge a law that forces providers of vital services to ALWAYS, no matter what, provide browser-based options, as well as low tech options for people who don't have access to any device.
Those who only provide a Google/Apple option and refuse the service to anyone who doesn't fit in those sets, while providing a service that could be easily served by a web app, ought to be fined.
