Not just as in Lemmy, but as in general.
Most of the time it’s the same thing.
I typically use apps if it’s something I’ll want to open on my own, and website for things I only ever open if I’m sent a link to it
Websites. I hate apps. I hate them trying to glean data from me, I hate then trying to shove ads down my throat while I’m already buying shit from them. I hate how I have to open a new app for everything instead of just another tab. I hate that many are tied solely to apps on my phone and refuse to use those platforms. I want to use my computer instead sometimes. Sometimes I don’t want to tippy tap on a small screen. I hate apps with a passion, they are a fucking blight more often than not.
I still need to use Reddit for one particular subreddit and more I’m annoyed the mobile web version has been taken away.
If its open source and privacy respecting then I’ll use the app. If its not and I have to use the service then website
I use the mobile versions instead of apps, largely because it’s easier to block ads and better for one’s privacy.
