she’s been acting weird and secretive with her phone lately, i think she might be tracking someone. how can i find out who she’s monitoring?
Honestly man, if you’re suspicious enough to want to secretly investigate her phone, that’s already a relationship communication problem no app is gonna fix.
The straightforward move is just asking her directly - “hey I noticed you’ve been weird about your phone, what’s up?” - awkward for 5 minutes beats months of paranoia.
If you’re genuinely worried she’s doing something sketchy, that’s more of a “do we trust each other” conversation than a tech problem.
