I'm talking from MY PERSONAAAL experience. I was reading the others reviews and I have to make my own. I have a little bit more than a month, since I download this app (demo), I did it because a friend of my suggested it.

I gave it 3/5, cause I'm still learning (and the normal couple of losses). I'll tell you more if something change
