Hiya Spam Blocker vs Who Called

Hiya Spam Blocker is an Android and iOS app for identifying unknown callers and screening or blocking unwanted spam, telemarketing, and robocalls. Its free version provides spam and fraud alerts, caller ID for known businesses and spam numbers, spoof protection settings, and blocking settings. Premium adds automatic call blocking, reverse number lookup, enhanced caller ID, Call Screener, and more frequent spam updates on iPhone. Premium costs $3.99 a month or $24 a year, and a 7-day trial is listed. Features vary between platforms: automated call screening is listed for iOS, while visual voicemail is listed for Android. Call Screener requires Premium and is available in the US and Canada on supported carriers; Android requires one active SIM. Individual non-business number identification is a Premium feature and is unavailable in Europe due to privacy regulations. Hiya also describes real-time voice analysis that warns about suspected deepfake voices during calls. It says newly emerging or spoofed spam numbers may initially go unflagged, and withheld numbers cannot be individually identified or blocked.

Who Called filters unwanted calls with an official telemarketer prefix list and community reports. Its Android and iOS apps can block risky numbers before the phone rings on Android, while uncertain numbers can ring with a warning. The website lets people check an unknown number’s reputation and report it. Reports can be submitted anonymously without an account. An optional SMS shield hides notifications from unwanted messages without storing or transmitting message content. The maker says the apps have no account, ads or third-party trackers, and that user data is not sold or shared. Personal blocking rules, settings and the local call-filter log stay on the device and are removed when the app is uninstalled. Lookups and reports send information to the service; lookups are not stored, while reports are retained for at most 365 days. The API is hosted in the European Union and uses HTTPS/TLS encryption. Who Called is open source, free at free, and support is offered by email in French or English.
