First, we tried FaceApp on Apple cofounder Steve Jobs. It did OK with adding a smile, but female Steve Jobs is terrifying and young Steve Jobs has purple lips.
A photo of Snap CEO Even Spiegel, on the other hand, worked perfectly. Female Evan Spiegel bears a striking resemblance to Natalie Portman...
...while female Jack Dorsey, Twitter's CEO, has heavy eyeliner and long hair. Dorsey's aged photo almost looks real.
Aged Beyoncé looks a lot like her mother, Tina Knowles-Lawson, but male Beyonce looks confused, probably because FaceApp couldn't quite figure out how to remove all of Beyoncé's long hair.
Facebook CEO Mark Zuckerberg looks great with a smile, but his female counterpart has some hair problems of her own.
Dwayne Johnson looks rather strange as a child, but aged quite gracefully. He even looks great as a woman.
