Google introduced Circle to Search earlier this year to select Android phones. It is a rather nifty feature that lets Android users quickly search for anything on their phone's screens by circling it. However, the feature did not make its way to iPhones which has been disappointing. However, in a somewhat unusual turn of events (more on that in a moment), iPhone users can get similar functionality.
It's not exactly 'Circle to Search' but you can call it a variation of it where you can screenshot anything on your iPhone's screen and it would kick off a Google Lens search.
