Some things completed in an app could be done on a real PC. But I cannot carry around a PC in my pocket nor can I use one in a lot of locations and situations. For example, I find myself using banking apps more than I use web browser counterparts.
Jay and I sort of smirk and joke about how an app is necessary for so many basic things in today's world.
Now, it seems, I can make adjustments to my home network's router via an app. I can still see some information by typing the IP in MS Edge to access the admin page. Yet, my TP-Link Deco X60s required that I set up the system by using the dedicated app.
If I accidentally dropped my phone into a river or ran over it with my car, I'd be up a creek. I don't like being so dependent on a particular device but I've very little choice. This is just how things are in 2022.
