Needs Updated to IOS 11 – iHandy Flashlight Pro Review

I purchased the Pro version of this app and I used this app quite a lot and loved it but when Iphone updated to IOS 11, this app quit working and said that the developer must update to work. I can't get an answer from them if they are or not. I have some of their other apps but if they aren't going to update then I don't see why I should purchase anymore of their apps if they aren't going to keep them updated.
