TrueSender is a mobile app designed to reveal the true origin and intention behind every SMS message received on a phone. It helps users identify if an SMS is from a legitimate sender or a potential scam, phishing OTP, spam, or government notice. The app verifies the real sender ID, checks the sender address registered with the Distributed Ledger Technology to detect spoofing, and determines the network operator that originated the message. Additionally, it categorizes messages as promotional, transactional, service-related, or government communication, helping users better understand message intent. TrueSender prioritizes user privacy by storing data locally on the device and requests only necessary permissions to function. It is especially useful for users receiving suspicious or unknown SMS messages and those seeking to protect against scams and phishing attempts.
