Duck Go not working in expanded search ootions

★★★★☆ Tina Moraza · Oct 25, 2022

Updated review 5 years later... I don't know what happened to this app. I used to be able and pull up the caller information or something close to it, but I always had something come back after the search. Now, nothing. Not a single thing comes back in search Google even says nothing found. Unfortunately I had to Uninstall because It's pretty much useless. Sorry. Just what I was looking for. . Straight forward and easy to use.

★★★★★ Gustavo · Apr 5, 2025

My girlfriend uploaded this app and it's really Informative. I like that also my peers may have written about a number I. discussions. Great features!

★☆☆☆☆ Tyler Misiak · Feb 11, 2026

Somehow through a lot of phones I've had this app for years... can't think of one single time it's said ANYTHING besides appears to be a cell phone or spoofed number.& now u hi-jack my entire screen for a stupid loud and pointless add. Worse than worthless

★☆☆☆☆ Shawn Ryan · Jul 20, 2026

This app NEVER has any info on any number that calls me! It seems to be a worthless app!!

★★☆☆☆ Brittany Michele Sullivan · Sep 8, 2022

Has anyone put a number in the free version and actually gotten any info back? I put 16 different numbers in and every last one came back as 'unlisted, spoofed, or a mobile number'. So, I tried a few numbers I already knew the info for, and only one came back with info. Just saying...
