Social network Reddit recently began blocking mobile visitors to its website while pushing them to download the official Reddit app, and it's fair to say that the move is not going down well with users. If you visit reddit.com on your iPhone today, you may see a new popup that can't be dismissed, asking you to "get the app to keep using Reddit".
AFAIK there are a few, “read only” apps. iOS has RDX, not sure about Android.
I’ve answered to a sibling comment, but I’ll duplicate here. Hydra is not read-only and works really well on iOS.
I use stealth on android. It’s limited. Gifs show as links. No where near as good as sync used to be. But still better than the website if I end up there via a google search.
