Good but needs to be updated

I have used the app for 4 years now and it has been the best radar app Ive ever used but now it is starting to get buggy and not working please update the app I dont want to get rid of it!the navigation does not work at all it just crashes and when changing your icons for saved locations, nothing pops up except a blank white screen and sometimes it tells me I have been signed out of my account. I cant really use the app right now so please update it for the iOS 10 users
