Geofencing with no internet/data connection

Hello, Is it possible to make an app that when closed and with no internet/data connection, if user enter a concrete area (detected with GPS), app send a push notification?

I thought yes but then I saw that: https://www.rfwireless-world.com/Terminology/What-is-Geofencing-and-How-Geofencing-works.html

It seems it is not possible?? (they are talking about android, but what about iOS?)

Thanks in advance for the help.

“Push notifications” go from server to device, so your question doesn’t make much sense.

If you mean “sends a notification to my server” then the answer is no - obviously due to the lack of internet connectivity.

If you mean “shows the user a notification” then the answer is yes - but it’s a local notification, not a push notification.

Hi, thanks for your answer. What do you mean exactly with "a local notification"?

If the user have its mobile phone in its pocket, screen off, can the mobile emits a sound and show a message? (local notification?)
