Should I Answer? vs Who Called

Should I Answer? is a community-based service and mobile app for identifying and guarding against unwanted calls, telemarketing, and expensive outgoing calls. Its database combines community reviews with phone number ratings and is refreshed daily. On Android, the app can check a locally stored database without an internet connection and can optionally block unwanted calls automatically. The maker warns that automatic blocking may not work on every phone model. On iOS, number ratings appear in CallerID during calls or in Call History through the call blocking and identification extension. The service is also available on the web and as an extension. The Android app requires Android 4.1 or higher; Android 6 and newer require permissions for contacts, call information, and drawing over other apps. The Android manual says the local database stores phone numbers and statistics, while user reviews can be downloaded from the web service. The Android plan is free. An iOS automatic database updates plan has no listed price and includes a one-month trial period and free phone number information search.

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.
