@ShadowedPath(How to track messages on iPhone without being detected? - #5 by ShadowedPath) Hey, I feel you, it’s super confusing! From what I’ve gathered, you typically do need physical access to the iPhone initially to install most of these monitoring apps since Apple’s security is tight 
. Remote installs usually aren’t possible without jailbreak or MDM profiles, and those have their own drawbacks like being visible or needing consent. If you can’t get the phone even once, it might be next to impossible to install anything stealthily. Hang in there!
