Alternatives to Truecaller and other caller ID apps
NoCall focuses on Ireland: phone numbers, user comments, spam categories and fast web lookup before you call back.
Quick answer
To find out who is calling in Ireland you can use, among others, Truecaller, Hiya, Clever Dialer, tellows, ListaSpam, OpenSpam and NoCall. They differ mainly in the data they use (community reports, directories, names suggested by users), what is free and what is paid, and what they do with your contacts: compare them below.
How to choose an anti-spam tool
Check three things: real coverage in your country, clarity of reports and how much control you want to give an app. For a fast check, NoCall shows risk, category and comments in the browser.
