Angry [Q] FastForward App for Android?

Hey, as some of you may know, there is an app called fastforward for ios. It essentially speeds up everything on certain apps. I've googled for a while now, and I couldn't find anything like that for android.
Btw, I'm not talking about an app that speeds up a video or changes your system time. I'm talking about actually speeding up a whole app itself.

I'm just wondering if any of you guys have found anything like this. I would love this and will love whoever finds something like this.
