The pop up begging for your pennies to remove the ads won't go away, even after paying. So i can't do anything with the app and it took my money. Pretty sad that there is a nagging, begging pop up that won't let you so anything on a so called free app. Most apps just tell you about the paid options, and allow you to use the limited free with ads, not this app.
