Mostly. I paid for both rif and reddit premium. My subscription to reddit premium runs out in early August, so as a long as rif still works (mostly) I'll keep it on my phone's home screen next to Jerboa and alternative between the two.
That said, reddit has stopped allowing the porn subs to be accessed from third party apps, or at least from rif. I expect other restrictions to follow. So I expect I'll be getting of rif altogether in a month or so. Eventually rif for tildes (TIF?) will debut and I'm looking forward to that.
