Sorry about that! Here it is on F-Droid. It is called Adresilo:

This app is really helpful with that, and allows you to pull up the coordinates to an address or specific location and share it with your mapping app.

Is it similar to ObtainX? I’ve been using that for the past few weeks as a replacement and have really liked it.
