The site asks you to upload a photo of yourself or someone else, and then it tries to guess how old the person in the photo is and their gender with face-recognition software. Although it's a lot of fun, it's definitely a work in progress. As far as our experience goes, it is usually pretty accurate with sex ... and not so much with age-guessing. If nothing else, How-Old is pretty good for a laugh!
