Why the hype – Truecaller: Spam Caller ID Log Review

I research top rated call screener/block apps for iOS and in the week I have used this app, including the 3 day premium trial. It did not block a single call nor did it show a warning of a possible scam, spoofed call etc. it is unclear if I have to keep the app open all the time or not. I can confidently say that in my case it was useless
