I figure most things don't need an app unless they are trying to take more data anyway. Anything telling me to install an app whose mobile experience is fine already is very fishy to me. I'm looking at you, Reddit.
So much this.
To add insult to injury, reddit intentionally degrades the site's experience in mobile devices with tons of dark patterns pushing users to their shady mobile app.
Facebook is my #1 example of this.
The app bloated up like it's primary purpose was to take up space on your phone. So I removed it and used the mobile website.
At first you had to refresh the page to get new messages. No big deal, but a bit annoying.
Then they updated and didn't even need to refresh the page to get an update to the thread you were in.
Then a few years back they decided you can't get messages in the mobile website, you must use their app. Later I learned about mbasic.facebook.com and have to switch to that when friends message me.
I agree that reddit might not need an app in the same way, but I'm sure there are ways they could improve their user experience by further leveraging mobile hardware in ways that don't relate to tracking.
I prefer "Reddit is Fun" which seems to load faster than mobile web reddit and notify me on comment replies.
That's a problem that reddit creates for itself as it purposedly degrades the site's experience on mobile devices with tons of dark patterns to try to push users to install the company's official mobile app.
