JoeCustoms.com tries to maintain accessibility and ease of use across multiple viewing platforms. For our forums we provide the option to use an integrated 3rd party app called TapATalk. This app is available for most mobile devices for $0-$2 depending on the device and service provider. It isn't necessary to view or interact on the forums, but it does allows users to do things a little easier, like post pictures.
However, tapatalk is only designed for forum interactions. It is not, repeat not, integrated with other aspects of the site such as, but limited to, the Custom Gallery, the JCwiki, or filecard creator.
