Crowfi

Crowfi for Mastodon is a third-party client for Mastodon, the decentralized social network made up of independently run servers. It lets you sign in to your Mastodon account and read your timelines, write and edit posts, and browse attached images and GIFs in a dedicated media viewer. The app is developed by an independent developer and is still at an early version number, with frequent small updates; recent releases have focused on details such as smoother GIF playback while zooming in the media browser and better line breaks while editing posts. It is aimed at Mastodon users who want an alternative to the official app on iPhone. Crowfi is free to download and offers optional in-app purchases. For iPhone Duo, the developer's release notes for version 0.32, published on the App Store on October 17, 2026, list initial support for the device as the first item. The notes do not say what changes on the Duo specifically, such as a different layout when the phone is unfolded, so DuoDiscover lists Crowfi as compatible for now and will revisit the tier if the developer describes more.
