Geotag Photos 2 - any good alternative?

Hi,

I was using their iOS and Mac OS apps and was very very happy with it.

Just found out that they stopped developing it, and it's gone from App Store.

I want to record GPS easily my iPhone and then easily add the metadata to my DSLR photos, so I can later import it into Apple Photos.

I don't want anything subscription based.

Any recommendations please?

Thanks in advance
