The one annoying thing about Lemmy over Reddit, is that you’ll open a link from somewhere on the web and the Lemmy Instance’s site loads instead of your preferred client app. Sync already supports around a hundred instances but there’s way more out there than that. However, there is a solution! Fediverse Redirect acts as a middleman that keeps an up-to-date list of basically all Lemmy instances, and then redirects all of them to your client of choice, including Sync! Just install the Lemmy Redirect app via APK or their F-Droid repo, and then follow the directions in the app to setup the redirects and which client to point to. I used the Shizuku method personally, but there is a manual settings method and a LinkSheet middleman method as well. No root or Magisk is required for any of the methods.

They also have a Mastodon version that does the same thing, but for Mastodon instances and clients.
