And you don’t realize that social media apps put cookies on other websites so they know you have been to another website and then start showing you ads based on your interests? Apps can’t tell what you do in other unaffiliated apps nearly as easily at least now on iOS that there is no globally unique identifier that apps can use to track you.

Apps require you to sign in so they've got you immediately. They can share all your activity with whoever they want. Websites (many) do not require you to login (youtube, reddit, hacker news, etc....) Apps also try to open all links into their own webview, a webview in which they can track all activity.

  Even if you don’t log in, Facebook can tell that you were looking for something on a third party site. And that was something that apps on iOS tried to do - see what other apps you were using by opening a url - Apple started restricting that years ago.

  > They can share all your activity with whoever they want. Ummmm.... You are aware of the GDPR? Your data cannot be shared with anybody without your explicit opt-in consent. If you choose to give this consent, then more fool you.

All privacy-respecting browsers block 3rd party cookies by default now, which prevents that kind of tracking. There's still other forms of fingerprinting they can use, but those can be used in apps as well.

  What are these other forms that apps can use?

      You realize you just made my point for me that websites can track you more easily than apps… FWIW: the website completely errored out on my iPhone until I turned my ad blocker off in Safari.

        Whoops, I misread your post, my bad. But I guess apps can run web views that have access to all the same fingerprinting as a standalone browser, minus any ad-blocking plugins (on iOS at least)

        With a browser, you have the ability to block cookies, block whole hosts/domains, alter DOM content, alter tracking URL's, and (often) disable low level features you don't like. With apps, not so much.
