NoCall
Identify spam calls and, with Pro, block them.
NoCall is free on Google Play (Android 10 or later) and on the App Store for iPhone. The free version identifies known spam calls (a label on iPhone, a notification on Android) and shows ads; Pro, a one-time purchase, blocks them automatically and removes the ads. The app asks you to sign in; on the website you can look up and report numbers without an account.
