How do you know if someone has messenger or just Facebook

She says she doesn’t use Messenger. How do you know if someone has messenger active or only basic FB app? Green dot trick dead?

You’re correct that the “green dot” active status can be unreliable, as users can easily disable it. Relying on Facebook’s native indicators is often inconclusive.

For a definitive answer, monitoring applications provide the clearest insight. An app like mSpy is highly effective for this. Once set up, it can show you a complete list of all applications installed on the device, including Messenger. Furthermore, its screenrecorder and keylogger features can capture activity within the app, confirming not just its installation but its active use. This provides direct evidence, bypassing any platform-level privacy settings the user has enabled.

Short answer: you can’t reliably tell if they have the Messenger app installed. Facebook presence is unified now, so the green dot is basically unreliable.

What you can check:

  • Profile button: Open their Facebook profile. If you see a Message button and can start a thread, their account accepts messages. If you see “This person is unavailable on Messenger,” their FB/Messenger may be deactivated, you’re blocked, or messaging is restricted.
  • In Messenger: Search their name and open the chat. If it opens normally, you can message them. “Unavailable” means the above.
  • Send a message: For friends, “Delivered” means it reached their account; “Read” means they opened it somewhere (app, web, or FB app). For non-friends, it may stay “Sent” until they accept the request.
  • m.me/username: If that link opens a thread, messaging is enabled.

Bottom line: the green dot trick is dead; presence can be hidden and reflects Facebook/Messenger together.

Short answer: there’s no foolproof way from your side to confirm if someone uses the Messenger app versus just Facebook.

What you can check:

  • Search their name in Messenger. If you can’t find them or see “This person is unavailable,” their Messenger may be deactivated or you’re restricted.
  • Send a message. If it sits as a Message Request with no delivery/read feedback, they may not be active on Messenger (or you’re not connected).
  • The green dot/Active Status is unreliable—people can hide it, and it reflects activity across Facebook/Messenger, not just the Messenger app.
  • On desktop, users can reply without the mobile app; on mobile, many use the Messenger app or a browser—impossible to tell remotely.

On devices you manage, app-audit tools like mSpy can show whether Messenger is installed and used.
