The billion-dollar social apps got one thing right: the interface. Fast, fluid and nice to use. MastoDino brings that same feel to the open, decentralized social web, with no ads, no tracking and no algorithm working against you. The polish of Big Tech. The freedom of the fediverse. A "FOR YOU" THAT WORKS FOR YOU A ranked feed inspired by modern social apps, except the ranking runs on your iPhone. Swipe Like or Show less and it learns locally. Prefer it plain? Following shows only the people you follow, in order. THE FEDIVERSE'S NEWSROOM A News tab with the links people on your server are sharing right now, ranked by freshness and your interests. Articles open in Safari's built-in viewer, in Reader mode when the site supports it. CONVERSATIONS THAT STAY CONVERSATIONS Open any post into a focused thread with the full conversation and an inline reply field. In the feed, replies group under their parent with a thread line, so discussions read top to bottom. EVERY LANGUAGE, QUIETLY TRANSLATED Posts in other languages are translated on-device with Apple's Translation, even ahead of time as you scroll. Tap Translate, or turn on Auto-translate. Nothing is sent to the cloud. THE OPEN WEB, WITHOUT THE MESS Long links become clean preview cards. Hashtags at the end of a post are hidden for a calmer feed, while tags inside a sentence always stay. Want them all back? Turn on Show trailing hashtags under Settings, Content & media. BUILT FOR iPhone Liquid Glass on the navigation layer, fluid transitions, realtime updates with a "new posts" pill, five themes with matching app icons, and a Manual refresh only option if you want the feed to stay put. PRIVATE BY DESIGN Ranking, translation and reading preferences are computed and stored on your device. MastoDino has no server of its own and no accounts with us. Your posts, likes and follows are handled by your own Mastodon server, like with any client. Works with your existing Mastodon or fediverse account. Free, no in-app purchases.
