The Best Keylogger Apps for Android and iPhone (2025 Edition)
A keylogger app records every keystroke made on a phone — from messages and emails to login attempts and searches. In 2025, keyloggers have become essential for parental control, employee monitoring, and digital security.
This guide reveals the best keylogger apps for Android and iPhone that combine accuracy, stealth mode, and legal compliance.
What Is a Keylogger App?
A keylogger is a software tool that tracks what users type on their devices. Modern keyloggers like mSpy and Eyezy can log text messages, social media chats, and web activity — all while remaining invisible.
These tools are legal when used for authorized purposes, such as monitoring your child’s phone or company-owned devices.
