Really helps reduce spam. I have a lot of calls from what could be called spam callers with weird names associated with them, and I give a trustworthy response even if not happy - one way or another - with the results of the call.

Doesn't work. I can't login using any of the methods. It'll just show a blue loading bar and keeps loading non-stop.

Hello, Ricky, Thanks for your query. Could you please tell us, did you install Nize from Google Play, or did you use another source?

I can only give it one star. It won't allow me to sign in due to [Firebase App Check token is invalid. ] error.
