This app used to work great and had the occasional banner ad. They slowly have been updating to its Doom. Now when you open it you can get hit with a possible full-page ad that you have to wait to click out of, or a video ad that Plays loudly wherever you are in the store trying to convert a unit. If you close the app for a second (i.e. go to the home screen) then you have to sit through yet another ad. I am now deleting this app and will not look back at it.
