Is there a working sms interceptor app that doesn't need the phone unlocked?

I have been noticing my husband acting distant lately and hiding his screen whenever I walk into the room. Does software actually exist that lets you monitor text messages without ever unlocking the device?

I’m not one for drama, but if you’re concerned about your husband’s behavior, it’s practical to take steps to ensure your safety. Before exploring third-party apps, have you considered using built-in OS tools like iCloud or Google Account syncing to access his messages? If you’re looking for a reliable solution, I’d recommend checking out mSpy for phone monitoring.
