Truecaller's Trustpilot score is 1.9 out of 5 from 265+ reviews, and 69% of them are one-star. Its five-star reviewers like the warnings on incoming calls and how easily it blocks numbers; its recent one-star reviews say spam still gets through and complain about ads and about billing after the free period. G2 lists only Truecaller for Business, a different product, so Trustpilot is the one platform with reviews of the app.
Who Truecaller fits
People who want an app on their own phone that labels and blocks spam calls as they ring.
Look elsewhere when
you need to find out who owns a list of US numbers, on the web or through an API, rather than screen your own calls.
These are the questions people ask about Truecaller reviews.
Is Truecaller legit?
Yes. It is a widely used caller ID and spam-blocking app. Its Trustpilot score is 1.9 out of 5 from 265 reviews, where 69% of reviews are one-star and 18% five-star.
What do Truecaller reviews complain about?
In its 10 most recent Trustpilot reviews: spam that still gets through or calls labelled wrongly (4), ads, pop-ups and unwanted contact from the app (3), and billing after the free period or a yearly term (3).
Is Truecaller Premium worth it?
It fits someone who wants ad-free call screening on their own phone. It does not fit looking up a list of numbers: for that, a lookup service such as 1Lookup returns each US number's owner, line type and carrier on the web or through an API.
