The Infinity app for Reddit is a multi reddit account Android client. You can sign to multiple reddit accounts and you can also use the apps anonymous account feature. The anonymous account is browsing reddit without being in any of your accounts and essentially just like browsing reddit in a inconigo tab and not being logged in.
You can already do that. Add instance to the list without logging in and select local/all feeds and you can just browse.
With this method your still logged into an account. And when your scrolling lemmy logged in, you may accidentally hit like on a post
I’m logged into Lemmy.ml, have the beehaw.org instance added, & viewing All@beehaw.org… I can’t accidently up or down vote, or comment, as this message is displayed at the bittom of the screen… So yes I am browsing this instance anonymously…👍🏻
But you cannot anonymously browse lemmy.ml since your logged in. If your viewing it under All@lemmy.ml, you cannot browse. So In this case you can anonymously browse on instances your not logged into and having this as the anonymous feature is very confusing.
