Great App Gone Bad

I was loving the app. I have been using it for months. As of the past 3 weeks I have not been able to open the app. It crashes every time I launch it. I have an iPhone 7 and Im on the latest iOS.

I literally cannot use the app any longer because it crashes within seconds of launching it. Ive tried looking for fixes, but for some reason nothing is working.
