Truecaller UI design & app screens

Truecaller is a caller-ID and spam-blocking app that identifies unknown numbers and filters unwanted calls and messages, hugely popular in India and other markets. It draws on a large crowd-sourced number database.

The interface centers on incoming-call identification overlays, a spam-flagged call log, a searchable number directory, and messaging tools. Clear flagging and blocking controls anchor the experience. It is a reference for communication-utility UX: real-time call overlays, presenting trust and spam signals clearly, and designing a privacy-and-safety tool that operates at the moment of an incoming call.
