When 'Who Called Me?' Saves Your Time
Common moments where a quick risk check beats a guess-and-call-back.
An unknown number rings twice and drops
A classic scam pattern. Run the number first and skip the bait callback.
'Your package is on hold' robocalls
Spot delivery and parcel scam scripts before tapping any link in the SMS.
Calls claiming to be your bank
Check whether the number has been reported for bank-impersonation scams.
Tax or police pressure calls
Government-impersonation scams use a small pool of numbers. See if yours is among them.
International numbers calling at odd hours
Lookup the country code and review whether the prefix is tied to known spam waves.
A 'missed call' you don't recognize
Decide before you call back — many scams rely on curiosity, not on a real conversation.

I get a dozen unknown calls a day. A 5-second check tells me which ones are robocalls. Game-changer for my focus.

Caught a 'package delivery' scam before tapping the link. The risk meter spelled it out clearly.

I forward suspicious numbers to my parents now. The lookup is easy enough for them to use too.
