Let me explain to you why there are so many negative reviews here so you can get the clear picture. There are obviously a few different things that are to be fixed. For instance, whenever there's a new mobile OS update, some features of the app become obsolete for some time before their dev team takes care of it. I know this because I had been using their app for over 2 years now. The app is great and all the features that do work are excellent. I'll just suggest that when you are going to buy it, contact their customer support and double check if they are still offering those particular features you're buying the app for.
