I don't think this app deserves good rating. First time, it works really good but after that it crashes and open advertisement first and then closes. I did it for about 20-24 times, ads, i closes the x button on ad, app closes and again open it it shows ad and the purpose of this app doesn't fulfill what it's made for. Taken into consideration and if others sees such things, time to flag this app as it's a possibility of having privacy data collecting.
