i just came across this post on twitter. it contains a link to the blogging service where roger posts news about their app.
As of March 15, 2017, Roger will officially be pulled from the app store and no messages will be sent or received. Here's the blog confirming it https://t.co/bZaHDyTjue
I must say I'm extremely sad to see roger go, as it's given me the opportunity to make some really awesome friends. I guess we'll see what happens next.
