Best android app for a twitch streamer ?

Hi!

I've been looking for an android app that can do the following :

• Display the number of viewers
• Display the chat
• Bonus : Warns me of new followers
• Extra Bonus : allow me to chat back

After trying many apps, I've settled with t'chat but it only does twitch chat. Displaying the number of live viewers would be a really neat addition.

To those who ask "why", the answer is simple : I don't have two screens, and as such must use my smartphone to be in contact with my viewers.

Thanks!
