Buran
★★★★☆
Ariane was a simple, fast, intuitive Gemini Protocol client for Android with a clean interface that quickly became my favorite mobile client. It was discontinued, forked first by the original author as a paid app called Seren (also discontinued) and later as a free app called Buran.
Buran hasn’t been updated since 2022, but it’s still available through F-Droid and still works great! Bookmarks and client certificates are both supported. It feels faster than Lagrange, though I’m not sure it actually is, and it doesn’t support subscriptions.
