Tapatalk was seemingly a love/hate relationship based on the feedback I got from many that used it, which FTR didn't include me.
The forum software has progressed to the point were it really didn't seem to offer much in the way of an advantage, especially based on the limited number of users. There are some quirks here and there, but we test to the best of our ability after software updates on both android and iOS and find the performance acceptable without the need for third party apps.
