iOS has the issue that you can not select default apps, unlike Android. So yes you can use a 3rd party app but you can't make it the app that takes pictures when the phone is locked nor can you make it the app that gets launched from the accessible from anywhere control panel. In other words, their is friction using a 3rd party app. But of course that's also part of the issue. If 3rd party apps don't have to make a sound then what was the point of the law? The perverts can just use a 3rd party app and 99.999% of users have to deal with a stupid for no actual protection.
