Be careful with the Marine Traffic web site. My understanding is that the data is on a delay for security purposes. This may be different from your phone I do not know.

I have no idea how a AIS system is going to pick up a position from a cell phone.

To either send or receive, it has to go through an internet-connected AIS proxy. This means you are required to have a usable cell signal to either get or send AIS data, and their system has to be operational and not lagging in data conversion. I would call this "better than nothing" but far from the same as real AIS equipment. But even the most basic AIS is $800, and this certainly beats having nothing.

If the signal is "up to an hour" late, I would think this is very misleading and could get you confused. I certainly wouldn't rely on it. This data come over the internet, not directly from other vessels.
