Want to see true caller ID? Block unwanted calls with this spam call blocker app
Senior reviews editor
HangUp is a caller ID and spam blocking app for Android, built by Nord Security and powered by NordVPN, according to the listing. It is aimed at people who get spam, telemarketing and scam calls. The listing says AI voice-changing tools have made those calls more common and harder to spot.
The app's job is to tell you who is calling before you pick up, and to stop the calls you do not want. It runs on incoming calls, so it works in the background rather than as a tool you open each time.
The build we hold is HangUp: A spam call blocker 1.4.0 (APKS split bundle) for Android 12L and up.

HangUp checks each incoming number against a database of known spam callers and telemarketers. When a number matches, it warns you which numbers to avoid. The listing says it also flags potentially harmful callers.
The warning says whether a call looks like telemarketing or spam, so you can tell a sales call from a scam attempt before answering.
Beyond warnings, HangUp can block calls for you automatically. The listing describes this as the app's spam call blocking function, and it works on the same database checks that drive the warnings.
Using the app requires a free Nord Account, which is created during setup. The listing gives no other sign-in or payment step for the blocking features.
The app keeps a count of the harmful calls it has blocked, shown as weekly, monthly and yearly totals in one view. This lets you see how much unwanted traffic has been stopped over time.
The listing also advertises 24/7 help for users who run into problems.
