About Chan

Chan is an open-source Flutter-based mobile imageboard browser for iOS and Android. It allows users to access and browse imageboard threads with features tailored for both mobile and larger screen use. Core capabilities include multi-column layout, WEBM playback and conversion, in-app web search for images, local saving of threads and attachments, automatic captcha alignment, reply navigation gestures, multiple tabs, regular-expression post filters, archive support for deleted threads, and a thread watcher. The iOS version is not yet available on the App Store, and the app defaults to a test server that requires manual adjustment of content preferences to access other imageboards.

Chan FAQ

Why isn't the app displaying the content I expect?
By default, the app is set up to browse a test server; you can edit your content preferences in the app settings to browse a different imageboard.
Why are some settings located on a web page instead of in the app?
This is to comply with Apple App Store guidelines, as not all settings are allowed to be modifiable within the app.
How can I quickly scroll to the top or bottom of a thread?
Tap the status bar to scroll to the top; hold the post counter at the bottom-right to scroll to the bottom.
Is something wrong or out of date?
