The UnZ-Cure app should not conflict with any other apps, it doesn’t really do that much. You indeed won’t have to modify existing apps, and my app does not override any capabilities. My app is only very shortly active to kick off the pairing process, after that you can safely disable or remove the app. The original app will handle everything and won’t know the difference. You can also safely update the original app without worries.
Only if you remove the UnZ-Cure app, you will need to re-install it if you add other devices that you want to add unsecure, so I disabled it myself to save resources.
