It's the number one religious app/channel downloaded and used on Roku (America) and at number 21 on its "Most Popular" list with over 27,880 ratings. This is more than the Mormon/BYU channel, TBN, and EWTN channels on Roku.
Of course this may mean little as these other religious channels are available from all the major cable outlets and some even over the air or have affiliates like the Catholic EWTN.
