Tapatalk is offering its older version for free for anyone who wants to pick it up. The new beta version is also free. It's not great on here because of the smileys but its still decent for other forums. I believe this is a limited time offer so pick it up now while its free and you should still receive updated versions in the future when it returns to paid.
