tapatalk 2 the interface is much cleaner, lets you do more, and also u can use swipes to move from screen to screen. it also has push support for when someone replies to a subscribed thread, and the forum sync between iphone and ipad works way better than the first version. if u are using 1 upgrade to 2, might take u a few mins to figure out where everything is but once u do its much faster and more intuitive.
