Compatible with iOS 7, 8 and 9
Also try, Fortune (Free)
Fortune is a feature rich client for 4chan. It features a modern UI and one of the most requested features, support for WebMs, among many others, listed below. Fortune's WebM viewer offers the ability to play WebM's with and without sound. Efforts have been made to carefully prevent WebM playback from pausing current media, as a result, WebM's will start muted and will not play back audio when the device is in silent mode.
Unlike the regular website, both mobile and desktop, the catalogue view offers the ability for the cells to be a custom height. In essence this will allow users to get a better overview of what a thread is about, this feature can be configured from settings and behaviour similar to the official site can be mimicked. Spoiler support is included inline and in the classic "web view" of the client, with the latter closer resembling official behaviour.
There are however a lot more features offered by Fortune, all of which cannot be explained in great detail. Please refer to the list below to obtain a good idea of some of the features, bear in mind this list does not outline every single feature, but summarises the more major features present throughout the application.
*Adjustable font size.
*Animated GIF support, with the ability to save to the camera roll as an animated GIF.
*Automatic thread refreshing.
*Batch or selective downloading.
*Blurring of the application switcher.

*Image and WebM caching to preserve data and processing power, with configurable cache life.
*Initial iPad support (in later releases the iPad will adopt it's own UI, making better use of the screen real-estate).

*WebM support with and without audio.
*More!
Support for Fortune has been tested on and designed for iOS 8 on both iPad and iPhone (4S and 5S).
iOS 7 support has been tested and changes were made achieve compatibility on iPhone 5, however, the changes /were/ iOS 7 specific (not iPhone 5 specific), thus Fortune should work with other models.
iOS 6 support has been largely untested; it may or may not work. While efforts have been made to prevent known incompatibilities (like using blurred views on iOS 6), not all cases have been tested. Due to changes in the API, further work may need to be done in order to achieve compatibility. As of now, there are no plans for compatibility, if there is enough demand, iOS 6 compatibility may be arranged.
Support for 4chan pass is planned and should be available in an upcoming update.
