Truecaller has finally introduced real-time caller ID support for iPhone users, a feature previously available only on Android. This update takes advantage of Apple's new Live Caller ID Lookup in iOS 18, allowing the app to securely retrieve caller information. With over 2.6 million paying subscribers, Truecaller generates significant revenue from its iOS users, despite having fewer subscribers on that platform. The company has also built a new server architecture for this feature, which utilizes homomorphic encryption. Truecaller continues to innovate its iOS app, addressing competition and enhancing user experience.
