It's actually amazing! I got it just because I saw it and thought "why would they make that?" But now as I have it I am actually going to keep it. It's so much more efficient. The one problem is that you have to grant the app lots of permissions (obviously) but if your like me and have no sensitive information on your phone, taking the risk is the right choice. Anyway, I doubt the app would do any harm anyhow. Great app. Highly Recommend.
