PLAYERLINE.
It's a free app that has treated me well over the past few years. It's quite fast (it monitors Twitter) and it's very customizable.

I've enjoyed PlayerLine the last two weeks
I cut the SleeperBot cord and downloaded Playerline, seems similar... Only downside is the alerts are behind a paywall. $2.99/monthly or $20 for the year. I haven't bit the bullet and purchased the "pro" version yet, I want to try it out first. But you can follow players and see a feed of news from the players you followed, plus it looks like its driven off news from RotoWorld.
Edit* news feed seems to be also driven off CBS Sports
