Great, if it wouldnt freeze!

This app works great if you never have to delete a list or move the list order around. Every time you try to do either of those tasks, it freezes. I have several blank lists I made in error by tapping one button and have no way to delete them. Its been this way for over a year and no updates. Did they stop supporting this app??
