You can set 1SE to automatically add the location of where you've captured your snippets as a caption in the iOS app.

To enable this, go to the app's Settings and toggle "Use Location as Caption".

You can manually search for a site or use your current location by tapping on the GPS button in the text field when adding a caption to your snippet.
​

Make sure to give the app access to your location for this feature to work correctly.
