Ivory is a native Mastodon client for iOS designed to deliver a polished social media experience for users of the decentralized Fediverse ecosystem. Built by the team behind Twitterrific, it brings the design sensibility and feature depth of a premium mobile app to Mastodon, addressing the friction that often discourages users moving from centralized social platforms to federated alternatives.
The app offers a highly customizable timeline experience with support for multiple accounts, multiple columns, and the instance-specific features that make different Mastodon servers distinct communities.
Ivory handles the technical complexity of ActivityPub federation gracefully users can interact across instances without needing to understand the underlying protocol. Advanced filtering, list management, and notification controls give power users the organizational tools they need for sustained use.
Ivory is particularly valued by users who migrated from Twitter and found that official and third-party Mastodon apps felt unfinished compared to polished commercial apps.
Its design choices reflect years of experience building mobile social apps interaction animations, readable typography, and thoughtful swipe gestures that make heavy daily use comfortable.
As the Fediverse grows, Ivory represents the kind of client investment that makes the ecosystem competitive with centralized alternatives.
