Call Insider app user reviews

Even before accepting the call, I knew, thanks to the app, that somebody is calling me with an offer to check up on insurance contracts. So I declined the incoming call without worries and saved myself a lot of nerves. Big thank you to the developers.

Xiaomi Redmi Note 11

The best app to find out who is calling you. Taking off one star for not being able to block calls, but overall a great app.

Samsung S21

I got a call regarding an ad on an auction server and the app helped me find out that it was a scam aimed at getting money from you through a fake website. To be honest, if it weren’t for the reviews in the app, I don’t know if I would have been able to tell.

Motorola Moto G32

It does what it’s supposed to. I say it’s great and thanks.

Samsung Galaxy A33 5G

Great app! It has a huge database with information on phone numbers. I have absolutely no idea where they get the information and why it is free! I hope it stays free in the future too.

Xiaomi Redmi Note 11S

Absolutely great – if only I had got the app earlier. 😟
