Notification system
There is a 'Game' open out there that is all about the RPOL app that some people have created. It works pretty well, took some time to get all of the community threads to stop showing up for me.
I think you just get it from the play store. I might have seen an apple version was up last time I was in that thread. I mostly just check new developments on it when they post an ad then delete it from my stickies.
