Did the creator of this app die over two years no updates

Where have the makers gone AWOL or something? They have not made an update for nearly two years!!! On iOS 10 there wondered nobody uses this that because the app does not work!!! All you get is the home screen nothing works just stays at the home screen in that is it. The last time they even touched this app is 10/16/14 now it 12/16/16.
