About this app

Truecaller’s powerful Caller ID identifies who is calling and why, so you can decide whether or not to pick up. Use the powerful dialer and recorder to call friends, family, or look up a phone number, and keep a recording of important calls. Truecaller identifies and warns you about scammers, telemarketers, and other unwanted or unknown numbers.

It blocks spam 98% of the time, which makes me happy. What's so disappointing is that when you try to place a call it takes way too long to achieve. If you are using your phone and get a call, it's impossible to answer bc by the time you DO answer,the call has been so long in receiving you can't answer but have to call them back.This is an app full of glitches and lags. I'm uninstall and moving on, which due to the best app I've found for blocking spam is disappointing. 😥

Ok, I'm on day one and already don't like the app. It takes forever to send messages to people. It doesn't show all info in group text. I DO like the fact that it cleaned up unnecessary text messages I had but for me to give you ALL the permission that you requested, you gotta do better than this. Very disappointed! 11/13/24 Unfortunately there is no option to update, this was the latest version.

MMS doesn't work for me. VZW and LG text apps displays MMS just fine on my phone. I like the other features! UPDATE-I've decided to cancel premium subscription. After "months" of working with them, the MMS messaging STILL doesn't work. It's sad because I really like that it has calling/spam blocking & messaging all in one, it's just that I get a lot of MMS messages and NONE of them are viewable!! NONE! So, I'm done, going back to the default phone app, which does sup MMS.
