Not working on iPhone 7 Plus under iOS 10.2 – Active Sonar Review

I should have looked at the date before downloading this--the app hasn't been updated since 2009. Seven years is a long time, and when I try to run this on my iPhone 7 Plus under iOS 10.2, it diesplays upside down (!) and with a large blank white rectangle obscuring most of the screen. Too bad, as it sounds like a good app to play with. The author really ought to either update this or pull it from the App Store.
