If you've been itching to try out Google Lens on iOS, now's your chance, because the tool is rolling out as part of Google Photos for iOS as we speak. The software update follows on from its introduction in Google Photos for Android, which happened earlier this month.

For those of you not familiar with the tool, it's basically a clever visual search engine: point Lens at a celebrity, or a landmark, or a famous piece of artwork, or a QR code, and it'll give you the necessary information about it. Snap Ed Sheeran in the street, for example, and you get links to his YouTube and Facebook pages, and so on.
