Used to be pretty good, but has gotten really buggy lately. The app doesn't work sometimes. And it randomly opens and closes in the backround forcing the app you are using to minimize. It's super annoying. I'm updating this becauee even though it's not as buggy, it's still unusable because now there are ads every 4-5 swipes. Instead of spending time with the app, the ads make me shut it down out of frustration after a few swipes.
