The RiF app still "works" at least for me. I can't log in or see anything I was subscribed to, but it works for browsing random subreddits.

Out of force of habit I keep opening up RiF. (Can't bring myself to uninstall it yet) I hope me and possibly others accidentally using it isn't costing talklittle any money from Reddit. If it is guaranteed that it is, I'll definitely finally uninstall it.
