I switched to this app because the free version seemed promising. I read the reviews especially about the app crashing when you try to manage groups from settings. I bought it anyway thinking that with such a good thing..surely the bugs would be fixed. I was wrong. It crashed every time too. So disappointed and feel that I wasted time and $. DO NOT PURCASE until the reviews are consistently positive. I have the 6+ phone and maybe the issue is with the phone. If the app would stop crashing it would be 5 stars --no doubt. Developers, if you are reading, please fix so I can up the rating--this would be an awesome app!
