Yotsuba

A 4chan browser for Android, with a media vault that outlives the app.

Yotsuba is a free, open source 4chan client and imageboard reader for Android phones, written in Kotlin with Jetpack Compose. It reads boards, catalogs and threads, saves images and webm to shared storage, keeps offline copies of threads, falls back to the archives when a thread 404s, and updates itself from the GitHub releases page. No account, no ads, no analytics.
